Wow, didnt know about that Older stuff.
A few other facts about Rem sleep that you may or may not know.
You of course have multiple REM sleeps, they can last anywhere from a few minutes, to much, much longer.
Everyone REM sleeps and dreams, however;
Someone who is woke up during REM sleep has a MUCH higher chance of remembering the dream as oppose to someone woke up later. (I myself almost never remember my dreams these days, which means near the end of my sleep I'm doing much more non-REM sleep).
IIRC they level of brain activity during REM sleep approaches that of an "awake" person. I think that's the case but I can't remember, it's been awhile since I was really in to this stuff.
Babies have a higher percentage of REM sleep of course... because they sleep more.
