I have the occasional lucid dream, although I have no idea what causes them to happen.
It's strange, even though the dream is lucid and I'm aware thAt I'm dreaming, I don't really have any control and nothing very much happens to my "dream body"(?). It's more like I'm watching a giant screen that fills my vision. This "screen" as I think of it, is more like a window in which I see/create things that just seem right.
That is to say, this screen is sort of like a window from the lucid dream, into just a normal dream... Does that make sense?
I've come to call the lucid dream world "living space"... Sometimes it gets really, really disturbing.
