Your favorite movie or TV scene that made you want to sleep with the lights on.
Movie: The evil clown scene from Poltergeist. I had stuffed animals in my room at the time I first saw it, and I had to put them in the closet before I went to bed.
TV: "Squeeze" from the X-Files. The scene where Tooms reaches down and steals Scully's necklace as she walks by.
