This version of the Bloody Mary Legend goes like this

A young woman died in a bloody car accident, her lovely face disfigured by the splitting glass.
Since that day, she takes revenge on all those who apply the following ritual to call her spirit.

Stand alone in the dark in front of a mirror and say her name 3 times or more, turn around in place after each time. She will appear behind you in the mirror and scare you to death.
