The Restroom

A woman went to the restroom. Inside, she saw a note on the door that read, 'Don't look left.' She looked left and saw another note on the left wall that read, 'Don't look down.' She looked down, and on the floor, it read, 'Don't look behind you, there's a ghost behind you.' She looked behind her and found nothing. After using the restroom, she went to wash her hands. As she was washing, she suddenly felt a chill down her spine.
