The Unknown

I feel like I'm being followed. A strange flash of a shadow in the corner, a banging on the door of an empty house, the sounds of my name being cried out when no one is yelling. I know what I believe in and I do believe in ghosts, but now I'm getting scared. Maybe that's the objective of this unknown party or maybe he/she/it/they doesn't mean to cause me any harm. But it's like something hanging over my head. It's hard to sleep not knowing if I'm going to wake up. Strange things have happened but never something this strange, never something this unknown.
