A childhood belief about under my bed

I used to believe that there were 3 people that lived under my bed. On the outside edge, there were two scientists. There were constantly scheming on how to do experiments on me but they could only reach me if I were to just walk up to the edge of the bed and get in. Apparently they weren't "allowed" to get out from under the bed, only to reach out with their arms. They also could only "get" me if while I was in the bed, I allowed my hand or foot to dangle over the edge. So I of course would run and jump onto the bed from as far back as possible. Then there was the Carrot Man. He was a happy guy that lived in the center under my bed. He had a long white beard and just layed there surrounded by carrots and eating them all day and night. I have no idea where any of these characters came from in my bizarre imagination. I am however a science teacher today. Go figure.
