When I was about 7 I used to be really scared of anything "bad" getting into my room at night while I was asleep. So I invented an ingenius method for keeping out the baddies: I put up my own imaginary "force-field" over my door and window. This involved drawing a square around the door or window with my finger. Of course, I had to turn the invisible ink on first by clicking my fingers. As soon as the square was complete, the force-field activated and only let good thing pass through (parents, dog, etc.). I have no idea where this protection method came from but it worked. I've never worried about "baddies" since.
