A childhood belief about i'm different

I used to look for evidence that I was actually the last person on earth and that everyone else was an angel sent from God to pretend to be human so that I could have a normal life. Vacations were usually the occaision on which this suspicion would crop up again because I would so often see something in another city that looked almost exactly like a place I knew very well back at home. I would imagine that maybe there was just a little piece of the earth left and when I was "traveling" all the angels would run around changing the "set". I remember asking my mother once if she was really an angel pretending to be my mother. She laughed pretty hard and then said, "Believe me, I'm no angel!"
