Maladaptive Daydreaming is the name for it. And I would guess most, if not all people do this to some extent; myself included. If it doesn't bother you or interfere with your life, you can tell the difference between your imagination and reality, and you're able to pull yourself out of it, then I think it's fine. I's just another coping mechanism. Anything can be good or bad depending on how it's used.
