At the age of 3 I believed in the "doorknob people". I could see an evil, grinning "face" in the doorknob at night with the way the light reflected off the knob & surrounding area and I thought they were watching me. I thought they would come "get" me at night when I was sleeping, but there were two ways to keep them away. (1) If you pretended to be dead, they'd leave you alone. (2) If you made use of --*ahem*-- autoerotic practices (naturally I didn't have a word for this at age 3!!) it would form a protective shield around you that they could not break through. I used both methods routinely at that age. ;-)
