A childhood belief about eyes

I used to believe that when you looked at something your eyes actually left your head and went to that object. I would sit on the couch and look at the television. If my brother were looking at the television I thought that I could push his eyes out of the way with mine. I also thought that if I were looking at the tv and someone walked into the room and I looked away my eyes would be traveling across the room and if they ran into someone they may not make it back to my head. I also tried to use that theory to my advantage to "hit" my brother with my eyes when he came into the room. I was willing to risk losing my eyes if I could just get one up on my brother.
