have only had a few in my lifetime. when they happen I am only partially in control, my unconscious is right there... ready to screw with me! Also it is hard for me to stay in them. will try touching things. Often if I try looking very carefully at things it becomes too bright to keep my eyes open, or something limits the clear seeing.

In lucid dreams I have come up with surprisingly clever ways to test the dream. In one I punched a large glass window in front of me... actually that was to exit a dream that was definitely looking like it was going south (hopefully I never get the idea to do that while awake). In another case, I decided to reconstruct a simple mathematical proof in my head. Oddly I was lucid enough to know that it was all garbage and I was in a dream. Still I am surprised that I came up with this test idea while IN a dream.
