I used to think that when I wasn't looking, inanimate objects would turn into monsters and watch me. Sometimes if I turned fast enough, I could catch them in their monster state.
I also used to think that if you didn't step at the end of an escalator, you would get sucked under. But it wasn't all bad, because there was a secret society of people that lived under the escalator. I tried many times to get sucked under, but to no avail.
