YMMV: Harold and the Purple Crayon
Nightmare Fuel: It's not a particularly scary book in the traditional sense; Harold is a little boy who draws things with his crayon and they come to life, and they're almost exclusively nice things. The creepiness comes later when you realize that Harold is the only real character in the book. The whole world is empty, except for Harold and his crayon.
