That's cool, i've always thought of having a "Time remaining" bar or a "Lucidity percentage" bar and a "Control percentage" one which is basically how much control you have over your dream, i haven't had those in a lucid dream, but i had the Time remaining one in a non-lucid dream. I've also thought about Lucidity pills and control potions and i'm going to try and create them in my next lucid dream. My guess is that they're gonna work if i want them to so..
