Thanks for the additional screenshots of the NO sessions Chu!
Seeing the two side by side really highlights the differences--fascinating results!
It rather amazes me that my brain can do such strange things without me knowing!
But, what is interesting is that I obviously go into some sort of different mode even BEFORE the session starts; I've always thought that, but there is something like evidence in these graphs. It also continues for awhile after the session, and I usually sleep differently (deeper and better) and have interesting dreams after sessions.
