I fell asleep watching a program about dreams last night. Before I fell asleep I was pretty interested in some of the dream studies they were talking about. They've done studies that have shown that people who have more REM sleep can solve problems that require creative thinking easier than people who had little to no REM sleep. More REM sleep hence equals more creativity. Other dream studies have shown that the part of the brain that deals with negative emotions like anger and fear tend to be more active than other parts of the brain during REM sleep. Studies have also shown that people who suffer from depression slip into REM sleep right away when they go to sleep which means its possible that dreaming more exposes you to more negative stimulus than other people which in turn makes you depressed. Is this why the creative artist types seem to suffer from depression? More dreams means more creative aptitude but also could mean more depression. I'm no scientist so I don't know if I can make that leap based on the studies done but it seems to be a reasonable conclusion to me. Who knows? Maybe I dreamt the whole thing.
