again, though we say we were dreaming, and are SURE we did or did not have REM sleep, we would have to have confirmation from EEG. otherwise, we can only think we are getting REM sleep.
I did observe my own traits and believe I can see indications of REM sleep based on waveforms, respiration rate, and tidal volume, taking cues from some studies that say what occurs to these in REM sleep. In the hundreds of dreams, only about 2% of them are at times where the other data doesn't match.
I am not so confident that I can even make an educated guess as to when/whether I am in deep SWS (slow wave sleep). Sorry, I cannot pass on to you any tricks to ascertain that.
I have read that SWS, also called Stage 3 NREM sleep, tends to happen earlier in the night and generally before REM sleep. Once you have gotten the 45 to 80 minutes of SWS, you'll usually not enter this stage again that night. More room exists in the later cycles (as you are not in SWS) for longer REM sleep, and that is what usually occurs.
Lastly, some medications and sleep supplements make a pronounced effect to decrease REM and increase SWS, or the other way around. Nearly all apnea sufferers have low REM or low SWS (or both). I have run into only one apnea sufferer that had higher than usual SWS and REM simultaneously.
Read up on what SWS does for you, and maybe then you will detect the effect of SWS and by that method you can deduce that you are having SWS.
Hope this helps,

You might look into the ResMed S+
I've been getting what I think is fairly reliable sleep stage information from it and when I print out the Hypnogram and compare it to my sleepyhead graphs, the REM stages seem to match up pretty well with my flow trace and what I would expect in REM.
I know it's no EEG, but at this point maybe as close as I can get ass far as knowing how much REM I am getting.........six months of data so far and seems pretty accurate as far as I can tell.
Thanks for all the replies...good info, I really appreciate it....
