When I was like eight years old, I was always scared of the movie "Halloween". You know, the guy with the white mask and black eye sockets. In one of the movies, a girl is hiding behind a door, and right before she dies, you see the guy walk by under the door, the room is dark and there is light outside so you can see his feet walk by. In my dream, I was in a hallway with hundreds of doors and I was running away from the guy. I chose a door and waited, few minutes later, I see his shadow under the door and wake up scared as hell.
