A lot of kids believe that their toys came to life when no one was around. I took it a bit further: I would lecture my toys, explaining to them that it was OK if they came to life in front of me because I wouldn't tell anyone and would keep their abilities secret, etc. Of course, they never did come to life in front of me, and I remember being deeply disappointed that they felt they couldn't trust me.
