in that last leg of sleep, after you've already woken up and say you'll sleep for another twenty minutes or so but it turns into an hour; that last leg of sleep where lucidity comes easily or at least your ability to run a muck or be creative, it is much easier to remember words, like when you're writing poetry, the same poem no matter what happens in the dream, or it influences the dream; it is much easier to remember words you've written in that last leg of sleep than it is to remember music
