Handling dream darkness: I've rehearsed IWL a technique of turning up an imaginary light knob in the palm of my hand using my other hand. Have yet to try it out in dreams that go dark. Also, putting on night vision goggles. Mostly I just stand there stupidly thinking of what I should do until I wake up. Once I yelled "LET THERE BE LIGHT" in a dark (but not black) room, and I got a little bit more ambient light. The other thing I want to try is patting down my dream body with my dream hands (my main stabilization tech) to see if I can bring my dream body back into the "light."
