When I was younger I had my bed against the wall (at the side of the bed) with the rest of my room to the other side.
Being scared of the dark at the time, I used to sleep facing the wall just incase I woke up in the night and would be confronted by some 'thing' in the other side of my room...this became a slight habbit and still face the same wall when I sleep.
