When I was younger I used to get paranoid about a lot of things, usually fixating on one thing for a while until I found a new thing to be paranoid about. I remember going through a phase where I thought that everyone in the world was an alien except for me, and that they all had a human form.
These aliens didn't like being in their human form, so would revert to their alien form as soon as I was out of sight, but were always in their human form around me to keep their secret. After passing someone going round a corner I would backtrack to try and catch them reverting to their alien form, but they were always too quick for me, turning back into their human form JUST before I could catch them... that went on for a while, I was a very imaginative child!
