Bloody Mary is a fairly classic sleepover game. If you somehow missed out on the “fun,” though, here’s how you play. Stand in a pitch dark bathroom facing the mirror and call Bloody Mary’s name three times. If it works, you might see her face. Depending on what she thinks of you, she could scratch at you or possibly even pull you through the mirror into her world.
PS: We do not recommend you to try them as we may never know the outcome.
