I have the exact same thing, so you're not alone in this regard. I make up characters (for other people's worlds, I do admit), and all of my characters also have a very, very detailed life of their own.
I also have a video-imagination (I'm not sure what the proper term for it is, but I can create entire movies/episodes in my head with absolutely everything from sound effects to dialogue), so I already have full-length episodes/movies about my characters moving around in my head.
I'm not sure if what you're describing is AS-related or not, honestly. It could be, but I'm not sure.
I'm exactly as you are describing. I make characters up in my head, and I give them a whole backstory and world. I have some sort of video imagination, though it's practically without dialogue, but instead, there is a vivid image that I can make stories and novels with. There is always music in my things, though.
If I try to write down my ideas, though, I always forget what I originally planned to write...
