I watched "Are you afriad of the dark?" when i was about 6 or so and there was an episode about the sand man stealing children by grabbing their legs and pulling them under the bed... after that i refused to just step into and out of my bed at night... i had to jump from or land 2-3 feet away from my bed... otherwise he just might grab me.
