Wow, I didn't know that...just curious, do you know how it shifts if you sleep less than six hours? I'm asking 'cuz sometimes I only get that much or less...^^; [/b]
well, I belive that sleeping happesn in sycles, and if you dont get enoguh sleep, you wont each REM long enough to refresh your body. You will just experince dreams in the NREM stage, and maby touch a few mintus of REM sleep....
