What is the creepiest and/or scariest thing you have seen/done/heard/read?

[Scarim Coral]

The one that is popping into my mind now is this manga Gyo. Ok truth to be told I never once read it but just looking at that manga just is nightmare fuel.
The manga is about some kind of an invasion of rotten fishes strap into insect like machine whichthey all give a revolting odor and it can infect human and in turn (pretty much a corpse at this point) are also strap into the weird machine aswell.

Pretty much anything by Junji Ito. I don't scare easily, I've read many books by Lovecraft, King, etc. but this guy just creeps me out... I get this crawling feeling on my skin when I read his manga...

Spoiler

You can read his probably mildest and well-known work here http://openawesome.com/junji-ito-horror-manga/enigmaofamigarafault.html

...I've heard of him.

Didn't he used to draw hentai?

Mine is similiar; he's not as well known, and his name's Shintaro Kago. If you decide to look him up, NSFW. Because he draws a genre of ecchi known as "ero guro". To give an example: One of his drawings are of a woman getting her digestrive track sucked out with a vaccum. Decidedly not erotic.

Some of his stuff is very, very unsettling. But perhaps the worst part about it is that, while he draws it "to shock people" and says he finds none of it erotic, someone, somewhere, does. And that's the worst part.

I suppose the scariest nightmare I've ever had was just of a child vomitting. In extremely viscous amounts. Until bits of her started comic out. Including a few very realistic bones. Until she looked at me, then her eyes gooped into her skull. Then she barfed that into a bucket. Then she got up and started asking for help. Then she died.

It may have been triggered by the dog vomitting 1/4 of a chicken. I was 6.

Also, patau syndrome!

Edit: The Fault of Amigara. Oh God... So, people go into holes that are shaped perfectly like them, but because the mountain they formed in is at an angle, they fall in, until at the other end, they become vaguely-human like abominations..

Nope. Not clicking that link. Nuh uh. Not doing it.
...can someone please spoil what happens in it for me? D:
OT: I spent way too long on the SCP site once, and that was terrifying. Probably the most scared I've ever been, though, was when someone knocked on my window while I was reading "Jeff the Killer".
Don't... don't do that, guys. Just don't.

Ok i can do it.
It's not that much of a scary story but it has one pretty nasty thing in it.

Spoiler

if you want the small spoiler:
Basically it has a really unexpected jumpscare. It looks just like a normal comic, but once you reach a certain picture it plays a nasty sound and has an animation.
Since it looks like a comic it is really surprising and creepy at the same time.

If you want the big spoiler:
There's a walking corpse. Once you reach a picture were the see the back of the head of the corpse, just the head of it turns around to face you and you hear a really nasty crackling sound, like neckbones doing something neckbones aren't supposed to do.
It's pretty creppy but after all just a jump-scare, nothing hard to get over.
