For more advanced lucid dreamers...a question.

So, lately I've been having this different kind of lucid experience. I wake up into the dream, fully lucid, but there's no sensory content. No sound, no vision, just my awareness floating in this endless black stillness, and my own thoughts. It's a very pleasant state, and yet there's this little voice in my dream head struggling to make something happen, for content to appear. It doesn't, though. So finally I just let go and float until I wake up. I still feel energized and amazed, even so!

I wonder if this is a lucid failure--not enough consciousness to produce a dream scene--or actually a kind of lucidity in dreamless nonREM sleep itself, which I have heard is pretty much impossible to achieve. I don't believe that it is the latter, myself, although I think that would be amazing.

I should add that I really am not motivated to have specific lucid experiences or perform lucid tasks anymore. I've experienced just about everything I have wanted to in my lucids more than once. Perhaps this is why this is happening. I don't set goals for myself anymore.

Anyone relate?
