A childhood belief about ghosts

I went to my cousins house for a sleepover with her and her best friend when I was 8. Her friend told me that if you said, 'Bloody Mary I killed your baby,' 5 times in a pitch black room holding a single candle while staring into a mirror, BM would appear and try to kill you. My cousin had long, black hair and pale skin, so when me and her friend tried the ritual in her closet, she opened the door and walked in, with red finger nail polish spread on her white nightgown. Her friend dropped on the floor and started crying. I did that and wet my pants. I WAS 8! When I found out it was her I was SO ticked off........ I'm still afraid of her closet though. :)
