What happens before REM kicks in?
I've read quite a lot about WILDing, and there's something I'm still fuzzy on: what happens before REM starts?
As best I can understand it, when doing a successful WILD, at some point there's a feeling of transition: vibrations, or a feeling of heaviness, or just an extra sense of peace. Does the NREM period start now?
For instance, say I wake up after 6 hours, after my 4th complete REM cycle. Under normal circumstances, it's my understanding that I'll have another 30-45 minutes of NREM sleep before the next REM period. When WILDing, do I have to wait those same 30-45 minutes after the transition occurs? I assume that period of time isn't as restful as normal sleep. Is it restful at all (after all, the body is sort of asleep), or is it "lost" time?
