When I was little, not only did I have an imaginary friend named Jessica, but I thought that all my toys were alive! They just didn't move- usually- when I was watching.
These beliefs came at different times, though; in between was the belief that there were people in my closet when the lights were off. They were very tall, dark, shadowy people. (In reality, they were my outfits and not moving around.)
