This is a true story told to me by my mother. It's not that long, but it scared me!
My mother told me that ever since she was a young girl, she saw a black shadowy figure in a big hat in her doorway. She could never make out what he looked like, but it was obviously a person (or was a person at one time). She says that he would never come through the doorway, just stand outside her doorway until he disappeared.
