Spider man dreams

I was talking to one of my boys, Martin, as we were drying dishes together. He had already showered and was in his spider man pajamas. He goes on to tell me that when he wears those pajamas they tickle him at night and so he dreams of spider man. In his dreams he is spider man and saves people and does good things, but if he is having a bad night then he dreams he is the bad spider man and he does bad things and kills people. So I asked him what about when he is in his other green pajamas, and he said that when he is in those he just has normal dreams, like he is a move person in the action movies.
