I had an irrational fear of the dark as a child. I always slept with a nightlight on because I thought that even a hint of light would keep the Satan and the demons at bay. I also would fall asleep to the radio on an easy-listening station, however, my mother didn't want EVP coming through the radio, so she made sure it was set to turn off within an hour (it had a countdown timer for sleep).
At the KH, I used to envision what I would do when anti-religious "terrorists" would burst through the doors with their machine guns and machetes and start butchering us. I would think to myself, "I have no where to hide when they come to kill us."
I was afraid of everything... something that my MUCH older siblings teased me about. But they have no idea the kind of horrors that went through my mind all through childhood. I thought that I had to sleep on my right side because the left side was "evil." I still have no idea where I came up with that one.
But yes, my youth was very warped much like everyone else that has posted on here.
