In a dream, it's possible to gain and lose lucidity repeatedly, and in varying degrees. In the "breaks," one concocts all kinds of nonsensical strategies to regain it. I suppose one of mine is arguing with others about the nature of consciousness and its relationship to QM. In the best case, other people catch on and contribute missing pieces of the puzzle, which alleviates remaining doubts that were dissuading me from pursuing it in earnest.
