The Bad Science of Dreaming

I caught a Weird Science blurb on MSNBC by Jeanna Bryner of, and I had to do a double take and shake my head in disbelief:
In general, scientists agree that dreaming happens during your deepest sleep, called Rapid Eye Movement (REM).
No, no, no!

Yes, scientists agree most dreaming occurs during REM sleep, but this is actually the least deep of the stages of sleep. You can also see a diagram on this page showing how REM is at the top, and you hit that stage (and start dreaming) at about 90 minute cycles. The deepest sleep stages are N3 and N4, signified by pronounced delta brainwave activity.

I knew neuropsychology would come in handy down the road.

I have contacted Jeanna Bryner on the subject.
