I like to daydream. I have a bunch of different daydreams, and they function sort of like a screen saver for my brain. If I'm not doing anything mentally taxing, I turn on one and tune the world out. I can still remember as a child imagining all my stuffed animals as a council, sitting in a circle and doing something. Most involve a faceless, nameless protagonist who has some sort of magical powers. There are almost never meaningful relationships, and never names, in these daydreams. It's kinda creeps me out, what this fact says about me. These daydreams are very similar to what I experience when reading a book, in form if not content. These stories always involve some sort of enemy that needs defeating. Most run several years, until I get bored of them. I use them to help fall asleep.

Hey, I have those too! I always assumed it was a natural outgrowth of normal kid fantasies (being a magical hero and facing evil, no meaningful relationships) that for some reason I just never gave up on. As I've gotten older I've noticed certain tendencies in the way my protagonist acts and relates to others that have given me insight into myself, and I've stopped using them as a sleep aid because sometimes the adventure was interesting enough that I would deliberately stay awake so I could keep generating the next part.
