Young Blonde Girl In Front Of The Big Mirror

A staple of childhood slumber parties is the game Bloody Mary, which involves chanting "Bloody Mary" three times in a darkened room while staring into a mirror. There are many versions of the game, but the general idea is that "Mary" will appear in the mirror and attempt to harm or kill the person who has summoned her. Thanks to a series of popular horror movies based on a supernatural killer who haunted mirrors, the phrase "Candyman" may be substituted for Mary.
Mirrors and animals
Experiments have shown that only large-brained social animals are able to recognise that a mirror shows a reflection of themselves.
