Did you have trouble sleeping as a child?

I had no problem sleeping as a child, but now, as a teenager, I find it more difficult. I find it hard to fall asleep in pitch black darkness, and I need a dim glow of light to fall asleep, either from street lights outside my window or from the light of my iPod. I also have to make sure all electrical appliances in my room are unplugged because I'm scared it's going to start a fire when I sleep...
