Brilliant website. And Bodily Oddity is a great name.
I wish I had kept a notebook of this stuff as a kid, I remember having a lot of odd experiences and sharing them with my friends, but it was so long ago now.
I think most of them were visual oddities.
I remember seeing floaters for the first time, and asking my mother about them.
"Oh, that's just [neighbor] throwing trash out the window."
The delights of growing up in Eastern Europe!
I also get these "worms", bright glowing white. I heard they might be white blood cells moving through capillaries, but why would they be glowing? I usually see them after cardio.
Another fun thing to do is to stare at one point until your entire visual field goes grey (the afterimage cancels out the image... "neurons get tired" or something), then slightly move back/forward or slightly rotate your head, producing very interesting patterns from the interference...
The geometric nightmares! I had those as a kid whenever I was very tired or had a fever, and kept having them until my late teens. Never seen them described and didn't know it was a thing.
Same here. I also recall them when I had fevers in my childhood.
I attribute them to the fact that, while trying to sleep with a fever, my eyes are half-open, and any sharp object becomes a visible geometric shape that my brain attempts to comprehend but almost fails to. I still experience them in adulthood. I’ve never had sleep paralysis, but whenever I think of people who have it, I imagine it feels as debilitating as these half-sleep experiences where you’re unable to move while your brain processes distressing memories.
“Geometric Nightmares” is not a scientific name. It is simply the name given to this phenomenon in forums [1][2] where people discuss and share their experiences.
Last time I stopped smoking cannabis I got these for a couple days. They are intense. The most recent was kind of like taking a slow rollercoaster ride through three black hole sized perfect spheres orbiting nothing. Another one was less geometric but was basically me getting sucked into a black hole. Both had this almost lucid dreaming feel where my entire sense of self became condensed into a single point... but I was still there, aware of what was happening... it was incredibly memorable.
Interesting. I recently discovered that my sister and I have identical geometric nightmares, down to every detail, while everyone else I mention this to thinks it's insane. I wonder whether there's a genetic aspect?
I had a recurring abstract nightmare as a small kid (don't think it was related to fever but I guess those were pretty common) which was basically about a line, gradually becoming messier and messier until it was all just a big jumble. I could never explain it to anyone else, but it terrified me for a time.
I'm wondering if "geometric nightmares" is a reoccurring dream I've had since I was a kid too, basically two cog-wheels linked with each other, but one is extremely huge and the other unbelievable tiny. I'd never describe this as a "geometric nightmares" though, but it does kind of sound similar.
Maybe there is something about "contrasts" as they all seem to be vaguely related to "big difference" basically.
I've heard these fever dreams referred to as big-small as well. I believe it's the same phenomenon. For me it was pillars from high up above, where they're all the same width, but one is also much bigger at the same time. Hard to explain... Just an odd feeling.
And, anecdotally, I have gotten a similar feeling reaching deep enough meditation.
An interesting story about the Photic Sneeze Reflex [0]:
it's one of the things that fighter pilots are screened for. The reasoning is that they can't have a pilot looking down and dark ground, look up to scan for enemy fighters and start sneezing.
Some people with the reflex can also have multiple sneezes in a row.
> Some people with the reflex can also have multiple sneezes in a row.
I think that is unrelated to the sun-sneeze reflex though, some people that don't have that reflex can sneeze multiple times in a row, and vice-versa too.
I think I just learned that I have this! I usually sneeze when walking out of the house into the morning sun. And regardless of what makes me sneeze, it's rarely just one or two at a time.
Yeah-- no kidding. When I was anosmic with COVID I couldn't eat much of anything. Food was just terrible. I still remember the soulless paste that was peanut butter. (Ugh. It was so bad...)
I also get floaters in my eyes sometimes which is weird because they appear outside your primary point of focus, which you move to get a better look, but because the floater is in your eye then it moves away as you shift your direction of focus. A strange experience.
I also get hypnic jerks in my legs when I am tired - the leg twitches - it's a sign I'm at absolute peak need for sleep.
I once revealed to friends that I get Pee Shivers, assuming everyone does - they do not and I was laughed at. :-)
The geometric nightmare thread is wild. Getting the same shifting shapes across unrelated people suggests it's wired into how the visual system fails, not learned.
I get the occasional Hypnopompic auditory illusion ( https://vester.si/bodily-oddities/oddities/hypnagogic-halluc... ). This is when you think you hear a sound as you wake up. For me it is normally an illusory door bell. It is very convincing. You rush down to the door and there is no-one there and my wife heard nothing. Maybe happens 2 or 3 times a year.
I also get the occasional weird nerve shock. It feels like an electric shock down through my collar bone. It lasts less than a second, is always completely unexpected and is quite unpleasant, enough to make me flinch. It doesn't seem related to what I am doing. Maybe happens 6 times a year. Didn't see it mentioned. Does anyone else get this, or am I just weird?
Headcanon: Cortisol spike right before you wake up. Brain goes, "something must have alarmed me", and cooks up phenomena: loud noise, feeling of falling/tripping, etc.
Funny, that happened to me just this morning, I awoke from some kind of alarm signal, very close by. But I could not find any possible source for it, so I am sure it was part of a dream. In fact I forgot about it until now.
About the second thing, I have felt something similar. Especially the part about it originating around the collar bone and neck. It's probably something like a nerve misfiring. I sometimes think it's weird that the body doesn't misbehave more often than it does, it's an enormously complex system after all.
>About the second thing, I have felt something similar. Especially the part about it originating around the collar bone and neck. It's probably something like a nerve misfiring.
Possibly. Or a pinched nerve.
I don't think it is a cosmic ray, or it wouldn't always occur in the same part of the body. ;0)
>I sometimes think it's weird that the body doesn't misbehave more often than it does
Hypnogogic and hypnopompic auditory hallucinations occur when you are falling asleep or waking up, so it might be something different if it is happening if you are in deep sleep. (not an expert on this)
The feeling that you haven't experienced something before, which should by all accounts feel familiar to you.
>A study by Chris Moulin of Leeds University asked 92 volunteers to write out "door" 30 times in 60 seconds. He reported that 68 percent of volunteers showed symptoms of jamais vu, such as beginning to doubt that "door" was a real word.
The artifacts from some of the AI-generated images are a pretty significant detraction. For a site with so many pictures of hands, so many of them being malformed or having the wrong number of fingers (hithhiker's thumb, palmaris longus) is really off-putting.
Awesome site! I didn't find canaliths on it so I might submit it to you eventually: roughly every winter I get vertigo when lying down, and apparently there is no "fix" except to "reposition my canaliths"[1].
I knew those as otoliths, and the vertigo they cause is so intense and annoying I never forgot the name: benign paroxysmal positional vertigo
Fortunately, the Epley maneuver is very effective, if done correctly. Unfortunately, if done incorrectly it can worsen the symptoms. It's all about identifying in which semicircular canal are the otoliths before moving them.
Another one I'm not sure how to fully explain: closing the nose without touching it.
I can fully block smells or breathing by doing something that feels like inflating a zone between the top of the mouth and the nose. When speaking it will sound as if I am pinching my nose without hands.
Comes in handy when having to face horrible smells.
I assume everybody can do it but many don't know how.
I would get that as well - I ended up at the urgent care a few times just because it was so painful and unsettling.
It was never diagnosed but I'm pretty sure it was costochondritis - something in my sternum area was inflamed and would give off this awful shooting chest pain.
When I see someone else jump or fall from a height, I sense the fall in the bottoms of my feet and my lower legs. I feel both the drop and the landing. It also happens if I approach a ledge or dropoff.
I thought this was universal. It's pretty easy to trigger for me, even quite abstract geometric shapes that look a bit like something falling from a height can trigger it.
I keep being surprised at both which feelings are universal, as well as which aren't. I think I know the one your'e talking about but from being kicked in the balls... For jumping I might have experienced it playing video games and falling further than I expected.
I can move my ears. But it's not ears alone, whole scalp skin seems to move and ears get pulled from behind as a result. I learned it from my uncle as kid though by trying to do the same as him.
You've been great with clicking yes/no on the oddities, and providing more examples! I've already added some more, and refined some texts. I'll give it some more attention after I'm home again later today.
Something not mentioned that I’m curious about, if I’m about to fall asleep and I happen to hear a loud noise nearby, I also see a flash of light with my closed eyelids.
Weird. A spike in blood pressure maybe? Can you do reproduce it consistently on purpose with an alarm or by holding something as you fall asleep that will make a loud noise when it falls?
Sleep Paralysis is for sure my favorite oddity. I've not experienced it in 20 years and I miss it. It happened about once a year when I was young and into my early 20s. Mine often had weird noises and hallucinations and creatures floating around. The first few times it was rather scary but then I realized it was pretty neat. The trick I learned is to tell myself I just have to move my toe.
Sleep paralysis is when you're having an intervention in the monitoring realm but your matrix being becomes aware while so. Sources can't agree if it's done on purpose or just the analgesic dosage that was too short.
Next time you have one pay attention to hear if there's sound of steps as if moving away from where you are.
I've never seen someone miss sleep paralysis before. I get it, but the hallucinations that people describe never happen to me. I just become aware that I'm about to wake up, but I can't yet control my body or even breathing. I always know not to panic, yet I always panic and try desperately to start moving. I can always see the room, but it's a dream version because my eyes aren't really open and it looks different once I'm truly awake.
I don't have much sleep weirdness, but when I'm about to fall asleep, I frequently imagine 3D object spinning and rapidly changing size. Kinda like the 3D TempleOS sprites [1], but 5x faster and increasing/decreasing size at the same rate.
I've experienced it once or twice, and mine was the classic "can't move, malevolent presence just barely in the corner of your vision". Once, I think I was actually still half-asleep-ish, and trying to yell and my wife woke me up.
Definitely not pleasant, even when I'm rationally aware of what's going on.
I had it happen twice that I can remember. Once I hallucinated that I had a third arm that snaked around to my desk lamp, and just last night that someone whispered "hello" into my ear. Apparently that last one's pretty common.
Ahhhhhh! Thank you for mentioning Precordial catch syndrome. I read about it some time ago, and experienced it several times, and then forgot what it was called. Even with the help of LLMs I was unable to re-discover the name of it.
Very cool site! It's got some Claude-isms but they're not overwhelming which leads me to wonder: how did the author get the overall aesthetic to be so un-Claude-like?
Please point out the claudeisms, I want to clear them all.
V1 looked like complete Opus slop, but since I make many little sites all the time I can get it to undo a lot of them, one at a time. I just explicitly tell it the aesthetic to avoid per-element (like the famous left border), and eventually it looks okish.
Edit: Ah and for text, Standard Technical English is a good instruction to give it, but I also told it to be dry and technical, and no embelish or do storytelling. And some manual editing out of cringe stuff still after that.
I don't think you can fix the Claude tells without rewriting everything on your own - but I do read/write a lot for work, so I think about voice a lot. Here's a handful of sentences that I feel a human would not have used but which are common Claude constructions:
"the alarming ones that are harmless" - We don't put dependent clauses at the end of sentences like this except for unusual emphasis
'quietly' - overused by Claude
the entries here are the moments where the guesswork shows - same as first example
"none of this needs damage or disease" - Also would be written differently as a human. Just try saying some of these things aloud and you'll feel odd
People downvote me when I say we're back in the "Geocities era" / "indie web" of the 90's and 00's, but LLMs have enabled us to build cool side projects to completion and give them love.
This is 100% a good thing.
I love this website. It's fantastic. I don't care if it's AI. The world is better for it existing.
I agree that this is an example of interesting and good AI usage. The person who made it obviously put thought into it. Unfortunately a lot of vibe coded sites do not have that same level of care
People were already building cool side projects to completion and giving them love before AI.
You get downvoted for being weirdly ecstatic about AI "enabling" things that were already possible, while not caring about the human element that AI lacks.
People that say "things [...] were already possible" don't dream enough.
Maybe you were born a few decades too late. I feel I was born (a few decades?) too early.
I want the world with cures for cancer, holodecks, brain uploads, immortality, jet packs, surfing on Titan, etc.
I legitimately enjoy the future we're hurtling towards. It's the most exciting thing that has ever happened to our species. I hated the world where "Apple iPhones" were the pinnacle of human achievement.
We might be able to vibe engineer our own iPhones in a few years. That'll be fun.
The fact that people who couldn't program can now build utilities and automations for themselves is beyond remarkable.
And for those of us who can engineer, we're making 10x, 20x what we were before. I'm filling my life with all kinds of fun side projects, toys, games, utility software, automations. I don't look at libraries and software packages anymore - I just build what I need.
This is like 3D printing for software.
I've built my own SRS software, my own music library, my own project management software, several agents, a video editor, a few toy video games, home automation software ... and I've done this all in a month.
I am so excited about everything I'm going to be building. Time was a limit before. There is no limit now.
> FFS we've stood on the moon.
And we slept on that for nearly 60 years. We're about to build cities there. Finally.
>The fact that people who couldn't program can now build utilities and automations for themselves is beyond remarkable.
Learning to program has never been easier or more accessible. Being able to build a website has been accessible to non-techies for years. I'll admit using an AI is convenient but "beyond remarkable" is pushing it. If anything it's a bit of a tragedy. In exchange for that convenience people are buying into a closed, third party mass surveillance infrastructure generating code they can't understand, can't repair, can't edit or redistribute. From a FOSS point of view AI is objectively worse than what we had. And that's not even getting into the flood of slop and disinformation destroying the web.
>I've built my own SRS software, my own music library, my own project management software, several agents, a video editor, a few toy video games, home automation software ... and I've done this all in a month.
I can't imagine you needed all of this done within a month and couldn't find existing solutions for most of it. It seems more like you're addicted than being productive.
And I still don't see the line between you vibe-coding a productivity app something something holograms and brain uploads and surfing on Titan.
>And we slept on that for nearly 60 years. We're about to build cities there. Finally.
No, we aren't. We're no closer to than than we were 60 years ago. If you think Elon Musk is actually going to accomplish anything of the sort I think you're bound for disappointment.
I can't read stuff like this, and I can't self diagnose anything online. Once I realized that everything is a symptom of cancer in some form, all symptoms will lead to cancer if researched thoroughly enough.
That said, really good job here for those that can enjoy it without inducing panic attacks!
For me, I'm pretty sure it's related to having just awful seasonal allergies as a child - I'd quite often get stuffed up and have an unfortunate amount of pressure in my sinuses and ears. So then I'd pinch my nose and try to adjust it, eventually realizing I didn't need to pinch my nose.
My mum taught me the ear popping thing, while we were traveling by air, to relieve the ear pressure.
I can do it on command but never paid attention to how before.
It's basically "yawning manually". There's a couple different muscles activating at the same time, most irrelevant to the popping, I can't control them individually yet. (Probably learnable, if I practiced I could probably get the pop more efficiently.)
But yeah, just yawn real wide, that should do it.
A lot of stuff is learnable, like I couldn't move my ears but taught myself how to do it because I was bored.
I'm not a diver but I suspect it can be learned. I have allergy issues that cause my ears to not equalize when allergies are hitting and I think I just learned how to do this. its just sort of muscle that can sort of be lightly controlled. Controlling one side vs the other I can't really manage.
I wonder about these sites that appear to be vibe coded from a simple prompt. Has the author even looked at the data or just did a little sample and figured that looks about right and hit publish
To either my credit or against it, wikipedia provides a lot of the raw data. However that makes you feel.
I've been making this list for years as markdown files with a few sentences and links to wikipedia (or xkcd for his visual field comic), but the site is indeed made with the help of AI.
I clicked on Supernumerary nipples. Interesting. In the Sources section, there’s a link to Mark Wahlberg’s Wikipedia page. There’s nothing about nipples on Mark Wahlberg’s Wikipedia page.
I experienced mild brain freeze as a child but it went away in adolescence. It doesn't seem pleasant so I don't envy those of you who get intense versions of it.
I'm surprised it's so few! I'm in the 60-70% here -- I've never gotten it (despite many deliberate efforts), but I've never known anyone else who seems to be immune.
This AI website has very weak sources for many pages.
As they said in school (and is still valid here) - Wikipedia is never to be your primary citation. This website commits the sins of citing Wikipedia and ONLY Wikipedia.
In this case, I'd prefer Wikipedia links that have sources. To be honest, this is also what students do when they can't cite WP directly, they cite or follow the sources.
This is a really cool collection! I feel like it needs a manual once-over though, particularly in regard to the images. Having even a handful obviously wrong images makes the rest of the site feel less trustworthy.
But more on topic, this site is a cool idea but with the lamest execution ever. Whatever effort you might have put into collecting these phenomenon is overshadowed by the lazy AI slop. It doesn't seem like you're earning anything from this, so you just donated money to Anthropic/OpenAI/whatever in order to underwhelm/revolt/possibly-mislead some people. You could've done that with a simple goatse link for free.
I know someone who can literally vibrate their eyes sideways. It is very odd to see. You can see his eyes rapidly moving left/right but only a centimeter or less.
I immediately looked up whether it had "piss shiver" and it did. It was disappointing when Cecil (Straight Dope) refused to investigate it.
(Don't suppose you'd include orgasmic quiver?)
Synesthesia is multifaceted. When I was a kid I used to feel a shape in my hand whenever I felt a certain emotion. That went away in my 20's. Later as an adult I guessed it was a kind of synesthesia.
Ooh this is the closest description I've heard to one odd thing I had which was a satisfying feeling associated with two specific thicknesses (one around the thickness of a school copy book, the other around the thickness of a school maths book). At some points it could be activated by thinking about the thickness but long gone now.
Also had 3 more complex emotions/feelings/states that were a blend of certain particular things, not always that connected. For example one was mostly a combination of memories of my grandad's past (he died before I was born), and the Ratchet and Clank level "Metropolis". Similarly, the actual feeling of these is now gone. Anyone else have something similar?
The closest I've heard to that was Brian Eno in his film talking about something similar he seemed to have growing up with the colour purple.
They left out "autoheadslap", the sharp pain you get whenever anyone mentions Nvidia and you smack your forehead as you remember cancelling your massive buy order back when it was $110 and had not split yet!! It is often accompanied by uncontrolled twitching and repeatedly saying "fuuuuuuuuu" as you bite your tongue.
I learned diaphragmatic breathing pretty early in childhood. Later, I noticed that whenever I got the hiccups, taking a deep belly breath early on, usually within the first two or three hiccups, would make them stop. Over time, I learned to do this unconsciously, so nowadays it's basically a reflex as soon as a hiccup starts. Since then, I haven't really had any hiccups longer than one contraction.
I used to have them as a kid, even long stretches that prevented me from sleeping. I don’t remember having hiccups in the last 15 years. It just stopped happening at some point.
I once met a guy who said the same thing and was convinced that this was the usual case, whereas me still getting them as an adult was very unusual (this came up when I got them, apparently his first time seeing an adult do so).
I certainly can't, and until now I'd never heard of it either (I'm over 40).
It's not uncommon to assume that other people's experiences are like one's own until told otherwise. For me, it took until at least age 10 before I realized that other people aren't near-deaf on the left side.
If you're going to mock me by repeating my own words on a different HN thread (https://news.ycombinator.com/item?id=49665394), at least make it make sense because this is not analogous other than the Claude-esque design (which to be fair could be better). There is human intentionality in terms of how the information is presented (e.g. using Astro.js) and wit and it is not verbose or the output of just telling Claude to output as much detail as possible, and per the comments from the author, fixing any Claudisms instead of embracing them.
edit: and apparently AI-generated site layout too. Either it doesn't bother me as much as the writing, or I haven't seen enough examples, but I didn't notice that.

Never knew that it was part of fighter pilot screening, that is interesting.
I'm the only one with the reflex in my family including parents and children.
They all think I am insane blaming the sun for my sneezes.
Do you like to eat? Or do it out of a sense of duty?
Yeah-- no kidding. When I was anosmic with COVID I couldn't eat much of anything. Food was just terrible. I still remember the soulless paste that was peanut butter. (Ugh. It was so bad...)

Indeed.
I get the someone pounding on the door at night thing, wakes me out of a heavy sleep. Never anyone actually knocking.
Hypnogogic and hypnopompic auditory hallucinations occur when you are falling asleep or waking up, so it might be something different if it is happening if you are in deep sleep. (not an expert on this)
Well, I wake up lol, so ??? But I definitely feel like I was awakened from deep sleep. Wieerd stuff.

Most of them are pretty good. He just has to hunt down the bad ones and fix them.
Generating those has been its own little project inside the project. Many iterations to go.
Awesome site! I didn't find canaliths on it so I might submit it to you eventually: roughly every winter I get vertigo when lying down, and apparently there is no "fix" except to "reposition my canaliths"[1].
It all goes away during the summer somehow.
[1] https://en.wikipedia.org/wiki/Epley_maneuver
I knew those as otoliths, and the vertigo they cause is so intense and annoying I never forgot the name: benign paroxysmal positional vertigo
Fortunately, the Epley maneuver is very effective, if done correctly. Unfortunately, if done incorrectly it can worsen the symptoms. It's all about identifying in which semicircular canal are the otoliths before moving them.
If I understand correctly this is the same as BPPV which is on there :)
You're right! I brought BPPV was just all benign cases of vertigo regardless of origin but the article does mention tiny crystals, good catch!
Ah great! I'll put it on my list to read up on. Thanks
Another one I'm not sure how to fully explain: closing the nose without touching it.
I can fully block smells or breathing by doing something that feels like inflating a zone between the top of the mouth and the nose. When speaking it will sound as if I am pinching my nose without hands. Comes in handy when having to face horrible smells.
I assume everybody can do it but many don't know how.
https://www.reddit.com/r/TooAfraidToAsk/comments/ysd5o2/is_i...
Everybody who can speak can do it because that's what you do when you say [k] or [g].
Oh great point this will go on the oddity once I add it!
Proctalgia fugax (https://vester.si/bodily-oddities/oddities/proctalgia-fugax/), also known as "shooty arse":
https://www.youtube.com/watch?v=USB90D7ywiE
The video is oddly comforting. "Everyone gets it!"
I remember reading about the phenomenon, that it was colitis (inflammation of the arse, presumably due to gut flora imbalance).
Random chest pains like you describe cause so much anxiety for me. And yet every time it turns out to be nothing.
I would get that as well - I ended up at the urgent care a few times just because it was so painful and unsettling.
It was never diagnosed but I'm pretty sure it was costochondritis - something in my sternum area was inflamed and would give off this awful shooting chest pain.
When I see someone else jump or fall from a height, I sense the fall in the bottoms of my feet and my lower legs. I feel both the drop and the landing. It also happens if I approach a ledge or dropoff.
I thought this was universal. It's pretty easy to trigger for me, even quite abstract geometric shapes that look a bit like something falling from a height can trigger it.
Lovely! I mean odd… I will look into it, thanks!
Is this not something everybody feels?
I keep being surprised at both which feelings are universal, as well as which aren't. I think I know the one your'e talking about but from being kicked in the balls... For jumping I might have experienced it playing video games and falling further than I expected.
I experience the falling feeling in my legs and feet as well.
I can move my ears. But it's not ears alone, whole scalp skin seems to move and ears get pulled from behind as a result. I learned it from my uncle as kid though by trying to do the same as him.
I can do each ear independently.
I was unable to do this, and was promptly angered by my own incompetence, and overcame it through sheer force of will.
(Made funny faces in the mirror for an hour.)
Fascinating site! TIL the human eye can detect polarization of light (search for “Haidinger's brush”).
You've been great with clicking yes/no on the oddities, and providing more examples! I've already added some more, and refined some texts. I'll give it some more attention after I'm home again later today.
Thanks to everyone!
Something not mentioned that I’m curious about, if I’m about to fall asleep and I happen to hear a loud noise nearby, I also see a flash of light with my closed eyelids.
>if I’m about to fall asleep and I happen to hear a loud noise nearby,
https://vester.si/bodily-oddities/oddities/hypnagogic-halluc...
>I also see a flash of light with my closed eyelids.
You might want to talk to a optician about that. It can be a sign of issues with your retina.
I see flashes in a dark room when I wake up, because I have PVDs (posterior vitreous detachment) in both eyes.
Edit: I just re-read your post. If they both happen together, I think it is something different.
Could it be that both noise _and_ flash are in your head, and like me you have Exploding Head Syndrome? https://vester.si/bodily-oddities/oddities/exploding-head-sy...
Weird. A spike in blood pressure maybe? Can you do reproduce it consistently on purpose with an alarm or by holding something as you fall asleep that will make a loud noise when it falls?
Yes, I have never tried to reproduce it on purpose, but it happens consistently enough that I would be surprised if it does not happen at this point.
It happens simultaneously with the sound, so I would guess it is purely a weird form of synesthetic hallucination.
Sleep Paralysis is for sure my favorite oddity. I've not experienced it in 20 years and I miss it. It happened about once a year when I was young and into my early 20s. Mine often had weird noises and hallucinations and creatures floating around. The first few times it was rather scary but then I realized it was pretty neat. The trick I learned is to tell myself I just have to move my toe.
Why do you miss it? It is usually described as being terrifying.
BTW sleep paralysis is likely the cause of many 'alien abduction' reports: wake up, can't move, presence in the room, sexual element (e.g. probing!).
I was prescribed Xanax for a bit and it gave me the absolute worst sleep paralysis imaginable, with nested false awakenings.
Sleep paralysis is when you're having an intervention in the monitoring realm but your matrix being becomes aware while so. Sources can't agree if it's done on purpose or just the analgesic dosage that was too short. Next time you have one pay attention to hear if there's sound of steps as if moving away from where you are.
I've never seen someone miss sleep paralysis before. I get it, but the hallucinations that people describe never happen to me. I just become aware that I'm about to wake up, but I can't yet control my body or even breathing. I always know not to panic, yet I always panic and try desperately to start moving. I can always see the room, but it's a dream version because my eyes aren't really open and it looks different once I'm truly awake.
I don't have much sleep weirdness, but when I'm about to fall asleep, I frequently imagine 3D object spinning and rapidly changing size. Kinda like the 3D TempleOS sprites [1], but 5x faster and increasing/decreasing size at the same rate.
1. https://youtu.be/LtlyeDAJR7A?t=451
Mine was always accompanied by the sensation of being watched. I could 'see' where the watching was happening, but not the actual thing watching me.
Also always accompanied by fear.
I believe sensation of a presence in the room is very common in sleep paralysis.
Interestingly the belief of what the presence is has changed with culture. It used to be demons, now it is more likely to be aliens.
I've experienced it once or twice, and mine was the classic "can't move, malevolent presence just barely in the corner of your vision". Once, I think I was actually still half-asleep-ish, and trying to yell and my wife woke me up.
Definitely not pleasant, even when I'm rationally aware of what's going on.
I had it happen twice that I can remember. Once I hallucinated that I had a third arm that snaked around to my desk lamp, and just last night that someone whispered "hello" into my ear. Apparently that last one's pretty common.
I've never seen the shadow man or anything.
Ahhhhhh! Thank you for mentioning Precordial catch syndrome. I read about it some time ago, and experienced it several times, and then forgot what it was called. Even with the help of LLMs I was unable to re-discover the name of it.
Here I am clicking on everything to see if I have it :D
Very cool site! It's got some Claude-isms but they're not overwhelming which leads me to wonder: how did the author get the overall aesthetic to be so un-Claude-like?
Please point out the claudeisms, I want to clear them all.
V1 looked like complete Opus slop, but since I make many little sites all the time I can get it to undo a lot of them, one at a time. I just explicitly tell it the aesthetic to avoid per-element (like the famous left border), and eventually it looks okish.
Edit: Ah and for text, Standard Technical English is a good instruction to give it, but I also told it to be dry and technical, and no embelish or do storytelling. And some manual editing out of cringe stuff still after that.
I don't think you can fix the Claude tells without rewriting everything on your own - but I do read/write a lot for work, so I think about voice a lot. Here's a handful of sentences that I feel a human would not have used but which are common Claude constructions:
"the alarming ones that are harmless" - We don't put dependent clauses at the end of sentences like this except for unusual emphasis
'quietly' - overused by Claude
the entries here are the moments where the guesswork shows - same as first example
"none of this needs damage or disease" - Also would be written differently as a human. Just try saying some of these things aloud and you'll feel odd
'unknown. nobody has counted it'

> One hypothesis joins the two.
People downvote me when I say we're back in the "Geocities era" / "indie web" of the 90's and 00's, but LLMs have enabled us to build cool side projects to completion and give them love.
This is 100% a good thing.
I love this website. It's fantastic. I don't care if it's AI. The world is better for it existing.
I agree that this is an example of interesting and good AI usage. The person who made it obviously put thought into it. Unfortunately a lot of vibe coded sites do not have that same level of care
What world are you living in where you’re okay with this?
Phoned in websites / AI slop is not a good thing.
Code something yourself on neocities.
This is not slop. It took effort. This is not a one shot fire and forget project.
Value != Effort:
Infinite randomly generated slop + The Algorithm = Extremely personalized value delivered
People were already building cool side projects to completion and giving them love before AI.
You get downvoted for being weirdly ecstatic about AI "enabling" things that were already possible, while not caring about the human element that AI lacks.
People that say "things [...] were already possible" don't dream enough.
Maybe you were born a few decades too late. I feel I was born (a few decades?) too early.
I want the world with cures for cancer, holodecks, brain uploads, immortality, jet packs, surfing on Titan, etc.
I legitimately enjoy the future we're hurtling towards. It's the most exciting thing that has ever happened to our species. I hated the world where "Apple iPhones" were the pinnacle of human achievement.
We might be able to vibe engineer our own iPhones in a few years. That'll be fun.
But building a website like the one posted here was already possible. you compared it to the early "indie" web.
There is literally nothing about generating websites with AI that merits being called "the most exciting thing that has ever happened to our species."
FFS we've stood on the moon.
> was already possible.
The fact that people who couldn't program can now build utilities and automations for themselves is beyond remarkable.
And for those of us who can engineer, we're making 10x, 20x what we were before. I'm filling my life with all kinds of fun side projects, toys, games, utility software, automations. I don't look at libraries and software packages anymore - I just build what I need.
This is like 3D printing for software.
I've built my own SRS software, my own music library, my own project management software, several agents, a video editor, a few toy video games, home automation software ... and I've done this all in a month.
I am so excited about everything I'm going to be building. Time was a limit before. There is no limit now.
> FFS we've stood on the moon.
And we slept on that for nearly 60 years. We're about to build cities there. Finally.
> And we slept on that for nearly 60 years. We're about to build cities there. Finally.
We're really, really not.
>The fact that people who couldn't program can now build utilities and automations for themselves is beyond remarkable.
Learning to program has never been easier or more accessible. Being able to build a website has been accessible to non-techies for years. I'll admit using an AI is convenient but "beyond remarkable" is pushing it. If anything it's a bit of a tragedy. In exchange for that convenience people are buying into a closed, third party mass surveillance infrastructure generating code they can't understand, can't repair, can't edit or redistribute. From a FOSS point of view AI is objectively worse than what we had. And that's not even getting into the flood of slop and disinformation destroying the web.
>I've built my own SRS software, my own music library, my own project management software, several agents, a video editor, a few toy video games, home automation software ... and I've done this all in a month.
I can't imagine you needed all of this done within a month and couldn't find existing solutions for most of it. It seems more like you're addicted than being productive.
And I still don't see the line between you vibe-coding a productivity app something something holograms and brain uploads and surfing on Titan.
>And we slept on that for nearly 60 years. We're about to build cities there. Finally.
No, we aren't. We're no closer to than than we were 60 years ago. If you think Elon Musk is actually going to accomplish anything of the sort I think you're bound for disappointment.
I can't read stuff like this, and I can't self diagnose anything online. Once I realized that everything is a symptom of cancer in some form, all symptoms will lead to cancer if researched thoroughly enough.
That said, really good job here for those that can enjoy it without inducing panic attacks!
Rare but useless Voluntary tube opener here. Ask me anything.
https://vester.si/bodily-oddities/oddities/voluntary-eustach...
Ooh! I also have this (but didn't know the name)!
For me, I'm pretty sure it's related to having just awful seasonal allergies as a child - I'd quite often get stuffed up and have an unfortunate amount of pressure in my sinuses and ears. So then I'd pinch my nose and try to adjust it, eventually realizing I didn't need to pinch my nose.
My story is similar!
My friend who does free diving would kill to be able to do it! She can't learn it.
My mum taught me the ear popping thing, while we were traveling by air, to relieve the ear pressure.
I can do it on command but never paid attention to how before.
It's basically "yawning manually". There's a couple different muscles activating at the same time, most irrelevant to the popping, I can't control them individually yet. (Probably learnable, if I practiced I could probably get the pop more efficiently.)
But yeah, just yawn real wide, that should do it.
A lot of stuff is learnable, like I couldn't move my ears but taught myself how to do it because I was bored.
I'm not a diver but I suspect it can be learned. I have allergy issues that cause my ears to not equalize when allergies are hitting and I think I just learned how to do this. its just sort of muscle that can sort of be lightly controlled. Controlling one side vs the other I can't really manage.
Ye ye, she is frustrated it's taking so long to learn it. It's so valuable for divers.
How is supertasting considered "rare" if it is 25% of people? https://vester.si/bodily-oddities/kinds/rare-ability/
You're right, I moved it
I wonder about these sites that appear to be vibe coded from a simple prompt. Has the author even looked at the data or just did a little sample and figured that looks about right and hit publish
To either my credit or against it, wikipedia provides a lot of the raw data. However that makes you feel.
I've been making this list for years as markdown files with a few sentences and links to wikipedia (or xkcd for his visual field comic), but the site is indeed made with the help of AI.
I get brainzaps sometimes, even when I take my SSRIs daily and with no withdrawal
I clicked on Supernumerary nipples. Interesting. In the Sources section, there’s a link to Mark Wahlberg’s Wikipedia page. There’s nothing about nipples on Mark Wahlberg’s Wikipedia page.
Only 30-40% of people encounter brain freeze?
Fabulous site.
So it seems, it just happens to include everyone I've ever talked to about it
I experienced mild brain freeze as a child but it went away in adolescence. It doesn't seem pleasant so I don't envy those of you who get intense versions of it.
I have to be so careful eating cold things, it's like freeze++, brain glaciation.
I'm surprised it's so few! I'm in the 60-70% here -- I've never gotten it (despite many deliberate efforts), but I've never known anyone else who seems to be immune.
This AI website has very weak sources for many pages.
As they said in school (and is still valid here) - Wikipedia is never to be your primary citation. This website commits the sins of citing Wikipedia and ONLY Wikipedia.
In this case, I'd prefer Wikipedia links that have sources. To be honest, this is also what students do when they can't cite WP directly, they cite or follow the sources.
This is a really cool collection! I feel like it needs a manual once-over though, particularly in regard to the images. Having even a handful obviously wrong images makes the rest of the site feel less trustworthy.
I agree, the images will need iteration.
It should be illegal to publish AI horrors like this: https://vester.si/bodily-oddities/oddities/gleeking/
Life in prison (at least)
But more on topic, this site is a cool idea but with the lamest execution ever. Whatever effort you might have put into collecting these phenomenon is overshadowed by the lazy AI slop. It doesn't seem like you're earning anything from this, so you just donated money to Anthropic/OpenAI/whatever in order to underwhelm/revolt/possibly-mislead some people. You could've done that with a simple goatse link for free.
I know someone who can literally vibrate their eyes sideways. It is very odd to see. You can see his eyes rapidly moving left/right but only a centimeter or less.
Don't know if this has a name.
Nah, it's cool.
I immediately looked up whether it had "piss shiver" and it did. It was disappointing when Cecil (Straight Dope) refused to investigate it.
(Don't suppose you'd include orgasmic quiver?)
Synesthesia is multifaceted. When I was a kid I used to feel a shape in my hand whenever I felt a certain emotion. That went away in my 20's. Later as an adult I guessed it was a kind of synesthesia.
Ooh this is the closest description I've heard to one odd thing I had which was a satisfying feeling associated with two specific thicknesses (one around the thickness of a school copy book, the other around the thickness of a school maths book). At some points it could be activated by thinking about the thickness but long gone now.
Also had 3 more complex emotions/feelings/states that were a blend of certain particular things, not always that connected. For example one was mostly a combination of memories of my grandad's past (he died before I was born), and the Ratchet and Clank level "Metropolis". Similarly, the actual feeling of these is now gone. Anyone else have something similar?
The closest I've heard to that was Brian Eno in his film talking about something similar he seemed to have growing up with the colour purple.
I started off having an nsfw tag, but it wasn't too populated, and decided for now to not include it. Might revisit.
>orgasmic quiver
very interesting google results for this one lol
This is delightful! What a nice and wholesome resource.
They left out "autoheadslap", the sharp pain you get whenever anyone mentions Nvidia and you smack your forehead as you remember cancelling your massive buy order back when it was $110 and had not split yet!! It is often accompanied by uncontrolled twitching and repeatedly saying "fuuuuuuuuu" as you bite your tongue.
Yes, a rare but real human affliction.
https://www.youtube.com/watch?v=f_SwD7RveNE
I remember choosing to not buy NVIDIA stock because Ethereum moved to proof of stake. Oops.
I remember waiting for that to buy a GPU.
Still waiting...
But just think of how many many things you could have bought with the same knowledge which would have been mediocre or failed entirely.
Do we have a theory yet why people hiccup? Wait, I just see you have a page on it :)
Not that I know of. But some people so far visiting the site have voted that they do no get hiccups, which is very odd.
I learned diaphragmatic breathing pretty early in childhood. Later, I noticed that whenever I got the hiccups, taking a deep belly breath early on, usually within the first two or three hiccups, would make them stop. Over time, I learned to do this unconsciously, so nowadays it's basically a reflex as soon as a hiccup starts. Since then, I haven't really had any hiccups longer than one contraction.
I used to have them as a kid, even long stretches that prevented me from sleeping. I don’t remember having hiccups in the last 15 years. It just stopped happening at some point.
I once met a guy who said the same thing and was convinced that this was the usual case, whereas me still getting them as an adult was very unusual (this came up when I got them, apparently his first time seeing an adult do so).
Have a friend who has never had a headache!
That is insane to me, as someone who suffers from chronic headaches every single day.
Huh, call of the void is common and it has a name!
Great site
Aw, a vibe coded site. Give Claude a cookie.
You should add "exploding head syndrome" which sounds crazy but is mostly "phantom loud noise especially as you're falling asleep"
It's there! :)
Is voluntary piloerection really that unusual? I thought everyone could give themselves goosebumps?
I certainly can't, and until now I'd never heard of it either (I'm over 40).
It's not uncommon to assume that other people's experiences are like one's own until told otherwise. For me, it took until at least age 10 before I realized that other people aren't near-deaf on the left side.
I can't do it either... Needs a good song or scene or situation to trigger it...
This should be taught in school.
Just because LLMs can write copy for webpages doesn't mean they should. A landing page should not warrant a tl;dr.
If you're going to mock me by repeating my own words on a different HN thread (https://news.ycombinator.com/item?id=49665394), at least make it make sense because this is not analogous other than the Claude-esque design (which to be fair could be better). There is human intentionality in terms of how the information is presented (e.g. using Astro.js) and wit and it is not verbose or the output of just telling Claude to output as much detail as possible, and per the comments from the author, fixing any Claudisms instead of embracing them.
How bizarre. He's attempting to troll you by leaving a negative comment on a different person's post?
The logic is supposed be that "someone else did the same thing as I did, so what I did was correct and your criticism is therefore wrong".
It's on me for randomly checking comments to see if people are acting in bad faith. Sometimes, they are.
Fascinating, but sadly LLM-assisted writing.
edit: and apparently AI-generated site layout too. Either it doesn't bother me as much as the writing, or I haven't seen enough examples, but I didn't notice that.
Or maybe you could start focusing on the content instead of how it's made.
