When i was little and my parents would watch scary movies, i was always afraid that they would come out of the TV and drag me back into the movie with them. So i would hide under the covers and try to lay really flat, so they couldn't see me. Of course now, I know this is not true, but I still fall asleep under the covers out of habit.
