Dream Recorder Anyone?

I don't know if its because I watch so many movies or because I have a wild imagination, but I've been having some really vivid dreams lately (as in the past few years). I wake up in the morning and I remember everything in detail but because I'm not really a morning person, I've never had the urge to write them down. I wish there was a dream recorder out there. Then I could record my dreams and write awesome screenplays and become rich & famous! =D
