I am doing a school project on lucid dreams, and R.E.M. sleep. I know that R.E.M. sleep occurs about every 90 minutes, and that once you wake up you should stay still and think about the emotions and thoughts you had in your dream. I also know what dream signs are, and I know (when I am awake) which signs are which. For some reason I can never put 1 and 2 together and I can never remember an entire dream. I might remember a flash or an emotion, but thats it. In the past 5 nights I haven't remember any dreams at all. What can I do???
