Solution to waking up during this is to wiggle your toes. I had sleep paralysis frequently back when I was toking on the herb. I was also experiencing lucid dreams a lot then. Oh and the best way to stay in a lucid dream is to look into your hands/palms if you feel yourself awakening. Tried and tested :)
I can't remember where, but I recall reading something about each person developing their own different "secret code" as to what should keep them dreaming or what should awaken them. It's funny that the brain should not accept direct commands but work with keywords.
