I used to believe that monsters were only able to get you if you were in the dark and it was completely quiet. This resulted in me either sleeping with the light on, or caterwauling any song that came into my head all night. My parents had to keep the lights on for weeks because I was terrified if I fell asleep with the lights off, the monsters would get me while I was vulnerable.
