Very cool website. I'm not sure if this is worthy of adding, but sometimes if I eat something extremely salty I get a pain in what feels like my saliva glands for 3-5 seconds or so after the first taste (it then goes away).

I think it's the same as in this reddit post where others describe it: https://www.reddit.com/r/DAE/comments/1hw4xx3/dae_ever_get_a...

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...

I should write a book...

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.

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.

I find this all fascinating as:

- I have this

- I was also born with no sense of smell

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 get those brain zaps from anti depressants.

Bzzzzzzt!

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. :-)

Oh. and I am a voluntary burper.

Now you know more than you ever wanted to.

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.

Since you have deja vu, you could add Jamais vu, the opposite.

Also prosopagnosia https://en.wikipedia.org/wiki/Prosopagnosia

Interesting site.

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?

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].

It all goes away during the summer somehow.

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.

Random chest pains like you describe cause so much anxiety for me. And yet every time it turns out to be nothing.

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.

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.

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?

Here I am clicking on everything to see if I have it :D

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.

How is supertasting considered "rare" if it is 25% of people? https://vester.si/bodily-oddities/kinds/rare-ability/

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.

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

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.

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.

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 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.

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.

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.

Do we have a theory yet why people hiccup? Wait, I just see you have a page on it :)

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"

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.

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.
