There is a legend that on Halloween night, if a woman walks up a staircase backwards while holding a mirror and candle, she'll be able to see her future husband's face in the mirror. However, she may also catch a glimpse of a skull, which means that she is destined to die before ever marrying. If that's the case, she may alter her fate by whispering a name while looking in the mirror three times: "Bloody Mary." Supposedly, a corpse-like woman will appear and - depending on how she judges the girl - will change her deathly destiny or make it happen much sooner than it otherwise would.
