What I liked about the whole lucid dreaming scene is that they already figured this out, but are using different terminology to describe it. You are exhausted, not relaxed, after a lucid dream. And you always need a second sleep session with REM sleep after that. But you make a lot of progress on internal reflections, because your subconciousness fills in the emotional blind spots your alter ego cannot grasp (yet). I think that's why a lot of people in lucid dreams can relate so much with the 2 systems theory of Daniel Kaneman, and why there's so much debate about it.
