For those who may not be familiar, the legend of Bloody Mary states that if you stand in front of a mirror and say "Bloody Mary" three times, the ghost of a woman named Mary will appear in the mirror. Some versions of the legend say that Mary was a witch, while others claim she was a victim of a violent crime. It is said, the person who performs this right is supposed to feel a presence of a third entity if uttered at the devil’s hour or 3 am.
