I would say he's just a big dreamer too, and may never grow out of it, My Pom Myndi is almost 14 and she still goes thru a lot of animation in her sleep, and it almost seems like a seizure. If I just touch her or give her a little nudge - it stops. She's not at all vocal in her sleep tho, but her "brother" Sparky is - he growls, wimpers, barks, and just about any other sound he can make, but has no movement to go with it, other than the occasional leg twitch.
