So iv been wondering with sleep be'ing so important and unknown, and there is usually a storyline of some sort in our dream, and to become lucid and just walk away from that storyline to do "fun" things. that storyline or dream in general could potentionally be important to whatever is going on and turning that into "fun" might not be the best idea.
You disrupt the storyline just with the simple realization that you're dreaming. Too late to regret it by then ^^
