A childhood belief about under my bed

My bed lay along one wall of my room. I was convinced that there were little people underneath it, who could climb up the wall and into my bed. My teddy bear was always beside me and the wall, and I thought that, if I went to sleep with my back to it, the little people would come up and steal him. For years I could only sleep on my left side, for fear of impending teddy-theft.
