A child's... game? Kids often at school or sleep overs will spread and test the rumor of summoning Bloody Mary. In a dark room, while looking at your reflection, you say "Bloody Mary," three times.

The low light of the room and the human brain's tendency to use short cuts makes your eyes perceive a distorted reflection of yourself after you stare at the reflection for a while.
