Bloody Mary (folklore)

An early 20th-century Halloween greeting card depicts a divination ritual in which a woman stares into a mirror in a darkened room to catch a glimpse of the face of her future husband. The shadow of a witch is cast onto the wall at left.

Bloody Mary is a legend of a ghost, phantom, witch, or spirit conjured to reveal the future. She is said to appear in a mirror when her name is chanted repeatedly. The Bloody Mary apparition may be benevolent or malevolent, depending on historic variations of the legend. Bloody Mary appearances are mostly witnessed in group participation play.
