since last nite 4.30am out with a m8, I have never considered lucid dreamin, but I'm so intrigued by it, the ablity to control you self in your dreams, flying, floating to places, going to other places flying, thats amazing, but here's the problem i see, what if the dream state attaches to you so much that you can't get back to your own reality, how would you know which is reality and which is a dream? is there some sort of a safety switch? a key word?
