When you were a kid what things did you misunderstand which lead to irrational thoughts or fears? For me two things really stick out - 1) I thought everything on TV was live, if I saw an actor on one station and then on another at the same time I couldn't figure out how this was achieved. 2) I recall asking as a young child what happens to all the pee and poo when you flush a toilet, I was told that toilets "eat" what you put in them. This scared me to death. For far too long I had irrational fears and even nightmares about toilets that would eat people or bite them while in use.
