I stumbled upon this article at slashdot (http://ask.slashdot.org/askslashdot/.../1956250.shtml) about polyphasic sleep. I'm not sure if this has been talked about here but basically, it says that we need less sleep because the only phase that we really need is REM. It states when you are somewhat deprived of the earlier stages in monophasic sleep you tend to go to REM sleep faster. You can read more about it

here: http://en.wikipedia.org/wiki/Polyphasic_sleep
and here: http://www.hackaday.com/entry/1234000573063569/

my question is, has anyone actually tried this, and if so.. were you able to achieve lucidity through this method?
