Not that I would be a fan of poly sleeping..I've been recently shifting to more early rising, so far it's enough for me:) But I love the idea of lucid dreams...one of the skills I want to learn. I've tested it few months ago, after about 3-4 days I had my first lucid dream where I partly knew I was dreaming&really enjoyed it(looked around my "dream world"). I have to learn this finally. Today I had "classical" dream where I was flying, I was so light that I could jump and the winds would bring me higher and higher - I flew very fast too and I could control my direction by legs..I flew over our village for a while..crazy!:D
