Yogi, I went through a phase like that. There was a vampire show on TV in the 1960s/70s called "Dark Shadows". I was NOT allowed to watch it because my mother knew what I was like. Sure enough, I would sneak to a friend's house to watch it. Then I wouldn't sleep without lights, a cross around my neck and the covers pulled up to my chin (to protect my neck from the vampire's bite!). It used to drive my mother crazy!!

Give him a night light and a kiss on the forehead from a sympathetic friend.
