When I was little, I had a very difficult time sleeping. And alot of the problem was from fear. So I started making up my own fairy tales in my head as I lay there in order to distract myself. I kept them very light and silly and full of beautiful things.
To this day, if I am having trouble falling asleep, and especially if it is because I am having worried thoughts, I will tell myself made up fairy tales. It works for me. But there is a problem with it. I never know how they end.....
