You may be thinking bloody Mary!! That's just a legend a folklore everyone knows Bloody Mary isnt real. Unfortunately you're wrong and Mary can be traced back to a real person. That's right folks a real living and breathing person that actually existed.
The folklore
She lived deep in the forest in a tiny cottage and sold herbal remedies for a living. Folks living in the town nearby called her Bloody Mary, and said she was a witch. None dared cross the old crone for fear that their cows would go dry, their food-stores rot away before winter, their children take sick of fever, or any number of terrible things that an angry witch could do to her neighbors.

Then came the night when the daughter of the miller rose from her bed and walked outside, following an enchanted sound no one else could hear. The miller's wife had a toothache and was sitting up in the kitchen treating the tooth with an herbal remedy when her daughter left the house. She screamed for her husband and followed the girl out of the door. The miller came running in his nightshirt. Together, they tried to restrain the girl, but she kept breaking away from them and heading out of town.
The desperate cries of the miller and his wife woke the neighbors. They came to assist the frantic couple. Suddenly, a sharp-eyed farmer gave a shout and pointed towards a strange light at the edge of the woods. A few townsmen followed him out into the field and saw Bloody Mary standing beside a large oak tree, holding a magic wand that was pointed towards the miller's house. She was glowing with an unearthly light as she set her evil spell upon the miller's daughter.
The townsmen grabbed their guns and their pitchforks and ran toward the witch. When she heard the commotion, Bloody Mary broke off her spell and fled back into the woods. The far-sighted farmer had loaded his gun with silver bullets in case the witch ever came after his daughter.
