There are at least 50 versions about the origin of bloody Mary in western folk. One of them said she was a witch, another said she was a crippled bride, and another said she was a bloodthirsty prophet.

Legend has it that calling bloody Mary can foresee the future. It is said that calling her name three times in front of the mirror will appear. Sometimes she is harmless, you will only see her reflection in the mirror, and she will answer your questions. Sometimes she is extremely cruel, grabbing people with nails and claws, tearing people's faces with fangs, killing people or forcing them to commit suicide; She can also trap people in the mirror and is famous for gouging out people's eyes. Different versions have different opinions.

Bloody Mary is a corpse, a witch or a ghost, usually covered in blood. If the summoning ceremony is not correct, ghosts will scream at the participants, torture and strangle them, steal their bodies or souls, drink their blood dry, or gouge out their eyeballs.

The two most basic factors in summoning are the mirror in the dark room and the exact number of times to repeat her name. One said that bloody Mary would only come on certain days, and the other said that she would splash water on the mirror, rub her eyes or hold a knife. Another version says that as long as you walk to the mirror in the dark, bloody Mary will find you whether she calls or not. When it comes to calling her, no one will appear, but the water in the bathtub will turn into blood, or see the wounds that don't exist on yourself, or foresee the future.
