A childhood belief about i'm different

When I was younger, I used to believe that my entire life was being filmed and all the people in my life were actors (like in The Truman Show). I would be in the shower or somewhere else alone and I would say, "I know you're there! I can see the cameras!" with the hope that the directors would give up. I also used to think that I was the only human on Earth and that everyone else were robots.
