As a kid I thought that if you are out past midnight, monsters would come out and eat you.
For a while, I also thought that the way jet engines worked was the fan is connected to a giant rubber band and was wound-up, like how if you stick a pencil through a rubber band, twirl it up and release it, the pencil spins. Yes.
I also used to think of my house as a sentient being and would talk to it.
...im starting to realize how odd I am now...
