When I was little I used to believe that when I went to the bathroom there were monsters hiding in the shower so before I sat down on the toilet I had to open the shower curtains and make sure there was nothing hiding in there. I also believed if I sang while I was on the toilet it would keep the monsters happy and they wouldnt eat me.
