Is Bloody Mary real? urban legend of Bloody Mary

For years I have heard about this scary ghost called Bloody Mary. You know at school when we were children people would talk about this game at lunch time. The story goes you turn off the lights in your bathroom light candles, and say bloody mary 3 times as you look in the mirror. Well then she is supposed to appear, you must run out of there before she scratches you with her evil claws.

Some people say it's fake. Some have seen her, some have felt her evil wrath. Yet others have not lived to tell the tale. I wonder if she is real? What do you think?
