Burroughs: Do you get any of your ideas from dreams?
Bowie: Frequently.
Burroughs: I get seventy per cent of mine from dreams.
Bowie: There's a thing that, just as you go to sleep, if you keep your elbows elevated you will never go below the dream stage. And I've used that quite a lot and it keeps me dreaming much longer than if I just relaxed.
Burroughs: I dream a great deal, and then because I am a light sleeper, I will wake up and jot down just a few words and they will always bring the whole idea back to me.
What Bowie describes is what he seems to be doing in the "Lazarus" video.
