A childhood belief about aliens

I was an easily frightened child... I used to think that there were aliens that would come late at night (I had very clear images of these aliens, which glowed in the dark.) However, I believed that they would only hurt you if they saw you. So I always slept with everything under the covers, even when it was really hot out, till I was pretty old. On other occasions, later on, I thought that perhaps the aliens could get me no matter what. For this reason I never opened my eyes after I had all the lights off. Not cause this would protect me; just so I wouldn't see them when they were about to kill me; I wanted to pass peacefully, and why scare myself when there was nothing I could do?

Wow, I was a fatalist child...
