REM sleeps. Dream about REM?

Question

Well I just heard about REM sleep and I don't really understand it. Also does it effect your dreams? On a different note the concept of my eyes moving rapidly scares me and I had a dream my eye was moving rapidly during sleep. It took me to a place where I only saw rainbow and everything was sketchy blackish it seemed like a regular Seattle over cast day just scenery of bare trees.I found it quite chilling because it was switching fron rainbow to seeing gray and the trees where just black. I am quite frightened I can't sleep.

Answer 1

 REM sleep is the deepest stage of sleep. In this stage you dream. As the night goes on REM sleep occurs more often for example if you get 8 hours of sleep you may have REM for the first time after the first three hours. Once more two hours later, and another two times the remaining three hours. The worst thing that can happen from REM sleep is a nightmare.

Now as for the dream it could be your subconscious telling you to bring some color or flavor into your life. The rainbow represents life and color in the black and white overcast setting you described. So get out there do something fun. See a movie, hang with friends, go to a concert, ect. If you mind your subconscious you'll most always feel more alive and enlightened if your everyday life.
