Last scary book I read was The Exorcist when I was in high school. Finished it about 3 in the morning and walked it out to the alley to throw it in the garbage. Couldn't stand the thought of having it in the house. I spent the rest of the night waiting for my bed to levitate - I was sure I was next. About 5 in the morning our cat jumped up on the open piano - I was so scared I literally could not move! Never again!
