Mary Bloody Mary

"You got to shut the light off in order to do that," Sarah said. "And say it like you mean it." She shut the bathroom light off and went over to the mirror. She said "Bloody Mary" three times with feeling. Nothing happened. Or so she thought. She seemed disappointed.
"Do you want to use the Ouji board?" Rachel asked, trying to make her feel better.
"No I just want to go to bed." That's when they heard the rapping sound coming from the bathroom closet.
"Rah," A little boy came out of the closet with a mask of a monstrosity. "Gotchya." He snickered.
"You little shit. I'm going to get you. I promise. When she turned away from the closet she saw her in the mirror. "Did you see that Rachel? It was her I swear to god it was her."
"No, your just tired and your little squirt of a brother just scared you," she started, "she does not exist. The mirror blew off the wall and shattered into the sink.
"See I knew she was real."
"If she is real then she wont leave you alone until she kills you. So you need to find a way out of this. You will be cursed for ever," said Rachel.
"She is right there, turn around," said Sarah.
"Where?" The lady from the mirror killed her, without hesitation. She started for Sarah next. Sarah backed up as far as she could and that is when she woke up.
