Topic: What are some of the scariest stories you've ever heard?

There are a lot of really, really creepy stories out there, especially on the internet. Here's a place to gather up the best if the best in one place. Wether they be a real story, from the internet, or something that "actually happened to you".
Just a few rules first, please abide by all the rules that Nintendo Life has set up; I don't want this locked.

So what are some of the scariest stories you've ever heard?

I know for me, one that comes to mind is 'The Showers'. I'm not sure where this was from ("no sleep" or something was the website iirc) but it had me terrified by the end. It's too long to put here, so I'd suggest googling it. Be warned, has minor swearing.

I don't hear too many scary things on the internet, but I have heard creepy theories on Zelda.

Just googled and read both parts of "The Showers" As well as being exceptionally written and gripping,it's also bloody creepy and I'm not easily creeped out.I've even been hunting on Google maps for its possible location haha.Cheers for that mate

I heard that Team Ninja wants to make another Metroid game!

@OorWullie That's the same with me, I loved reading it. It gave me the chills. ._."
It's literally, "bloody" creepy.

One time, a gurl told me she doesn't think Mel Gibson is a hunk. I tried to convince her with facts (I told her Mel was nominated as the sexiest man ALIVE in 1995), but in the end, it did not work.

It was unbelievably horrifying.
