When I was younger my parents would always let me read in bed for a little bit, then come to tuck me in. I always believed that at the exact moment that they shut the door behind them, when the lights were out and I was supposed to be falling asleep, my head had to be under the covers. I thought that everything bad in the world: ghosts, monsters, dead bodies, etc. were let out of their daytime confinements at that exact moment. This fear of that exact moment continued from the time I was five to age 10...
