Bloody Mary... I played that during a lock-in at my elementary school just for the fifth graders of course, as it was celebrating our time almost being up in elementary school (a lock-in, is a large, supervised slumber party, basically). Well, now I don't know if it WAS Bloody Mary, but something definitely happened. So much so that one of my friends was scared so much, that her parents had to home school her. Well, my two friends and I were bored, and so we started telling scary stories. I can't remember the exact time, but I think it was around eleven thirty. All of the kids (there were about forty of us) were piled into the cafeteria/gymnasium (it was one huge shared part of the building)... and we were bored.
One of my friends, Monique, told us about Bloody Mary, and how if you said her name three times in a dark bathroom, looking at the mirror, and have the taps running at full... she'd appear in the mirror. Monique told us that if you could stare her down, she'd grant you a wish. So the three of us hopped up, got a chaperone to escort us to the bathroom, and off we went. The guy chaperone stayed outside, and we went in.
On getting in, my other friend Shannon and I got too scared, and said nevermind, so we both went into the stalls to use them, leaving Monique out by the sinks (and the three HUGE mirrors behind them). Midway through 'going', all the taps turned on and then the lights turned off! I couldn't believe Monique was going to do it! I heard Shannon shout "NO!", and we both got out of the stalls around the same time, just as Monique was saying Bloody Mary for the third time. What I saw next gave me nightmares for about 5 years.
Through the moonlight (and light posts) coming through the window to my right, I could see the water coming out of the taps didn't look right. Not daring to look in the mirror, I approached to see that the water looked black. I put my hand under one, and the water was luke warm and thick. I looked over at Shannon, who was staring hard at Monique. Monique had this odd look on her face, with her mouth in an 'o' shape. Before I knew what was happening, the mirror directly in front of Monique cracked, and shattered onto the floor...
Monique had a piece of the mirror in her hand (although I never saw her bend down to pick up a piece), and was dragging it across her wrist... And the same black stuff that was coming out of the taps started to leak from her wound (blood from the taps... Blood from her wrist). I couldn't help myself, I was frozen to the spot.
Finally, Shannon seemed to break free of the spell she'd fallen under, screamed, and the male chaperone flew into the room, flipped the lights on, and as soon as the lights came back on, it was as if nothing happened. The taps were off, the mirror was unbroken...
But Monique was still bleeding from the wrist, and I still had blood on my hand from the tap. I quickly moved to the sink to wash it off (thankfully the chaperone didn't notice my hand, otherwise I think I would have been blamed for Monique's injury), and watched as Shannon just shook her head no, as if she were trying to shake out the sights she had just seen.
The man saw to Monique, who hadn't cut herself too deeply, so he bandaged it. Monique told him that the lights went off and she tripped. Shannon said nothing. I said I didn't know what happened, just that the lights went off while I was going pee. I knew that I hadn't imagined it, because I could see in the other two's eyes that they knew exactly what happened.
Monique's parents were called, and they took her home. Shannon didn't speak to me for the rest of the night, and I just ended up trying to sleep. But I couldn't forget what I'd seen, it kept replaying every time I closed my eyes. Shannon went home the next day... And didn't come back to school.
When I asked about her, the teachers told me she was being home schooled, and wouldn't be back. One day while out shopping, I saw her parents, whom I knew, and when I approached them and said hello, they blanked me, and walked off. Monique never spoke about that night, and we drifted apart. I remember one day I tried to talk to her about it, and she told me I was crazy, and that I didn't know what I was talking about. She actually threatened to beat me up if I mentioned it again.
I'll never know what it was that she saw in that mirror, or be able to explain what I saw happen, when the physical evidence after the fact seemed to prove my observations false. I swear this is true, and even though I don't know if it was Bloody Mary, or just an evil presence who saw it's opportunity to strike at three innocent girls (which could very well be, as it was a Department of Defense school in the UK, and on a USAF base which used to belong to the RAF, and had played a pivotal role in WW2), I just wanted to share this experience...I'll never forget it.
