R.E.M. sleep

i'm Today I slept for a little extra time and had a bizarre dream. It's amazing how much clearer things are, and how much more you just feel "yourself" after a good rest including lots of R.E.M. time. I'm about to wax extrememely geeky here, but there was a Star Trek episode I watched in high school where all the members of the crew were being deprived (by aliens I'm sure) of R.E.M. sleep, and they all started to go crazy. Wikipedia didn't have anything to say about that, but I'm wondering about the psychological effects of R.E.M sleep deprivation. I mean, today I woke up feeling creative and productive, with interesting ideas to spruce up my house (well, in Kim world, that means buying a cactus and some cheap Mexican art posters), and a good memory of some of the chores I need to finish before work. All this because I dreamed that American Idol auditions were held in an old church (interior painted two shocking shades of blue, with lots of those scalloped-edge bulletin boards in the Sunday School area), and that I missed auditions, but Simon let me sing for him anyway. I went backstage into an old theater, and stood on the stage while Simon sat in the house. He put me through to the next round, saying "it's definitely not your looks getting you through!"
I wonder if I sang in my sleep?
