Read the myth and folklore about her below.
In folklore and children's street culture "Bloody Mary" is a game in which a ghost appears in a mirror when summoned. One of the more common ways participants attempt to make her appear is to stand before a mirror in the dark (most commonly in a bathroom) and repeat her name three times, though there are many variations. Some include chanting a hundred times, chanting at midnight, spinning around, rubbing one's eyes, running the water, or chanting her name thirteen times with a lit candle. In some versions of the legend, the summoner must say, "Bloody Mary, I killed your son!" or "I killed your baby." In these variants, Bloody Mary is often believed to be the spirit of a mother (often a widow) who murdered her children or a young mother whose baby was stolen from her, which made her go mad in grief and she eventually committed suicide.
In stories where Mary is supposed to have been wrongly accused of killing her children, the querier might say "I believe in Mary Worth." This is similar to another game involving the summoning of the Bell Witch in a mirror at midnight. The game is often a test of courage due the violent consequences if she appears. It is said that if Bloody Mary is summoned, she will kill the summoner in ways such as ripping the face off, scratching the eyes out, driving the person insane or bringing the person into the mirror with her. Some versions say that if you chant her name thirteen times at midnight into a mirror she will appear and you can talk to a deceased person until 12:01, when both apparitions will vanish. Other variations say that the querier must not look directly at her, but at her image in the mirror. She will then reveal the querier's future, particularly concerning marriage and children.
Bloody Mary Worth is typically described as a child-murderer who lived in the local city where the legend took root years ago. There is often a specific local graveyard or tombstone that becomes attached to the legend. On the other hand, various people have surmised that the lore about taunting Bloody Mary about her baby may relate her tenuously to folklore about Queen Mary I also known as "Bloody Mary", whose life was marked by a number of miscarriages or false pregnancies. Speculation exists that the miscarriages were deliberately induced. As a result, some re-tellings of the tale make Bloody Mary the queen driven to madness by the loss of her children. She is also confused in some versions of the story with Mary, Queen of Scots.
While, as with any sort of folklore the details may vary, this particular tale encouraged young women to walk up a flight of stairs backwards, holding a candle and a hand mirror, in a darkened house. As they gazed into the mirror, they were supposed to be able to catch a view of their future husband's face. There was, however, a chance that they would see the Grim Reaper instead. This meant, of course, that they were destined to die before they married.
