Thread: Exploring Delta Sleep

I agree with you sageous, the true delta state would most likely start after the room shuts down. That would mean that at that point delta waves would be the predominant waves. Before that in the state I am describing, I think though, that delta waves begin to emerge and are present in the brain together with other waves. But I can't prove that unless I hook myself to EEG, and if that happens I probably won't be able to meditate at all.

One thing I forgot to mention, why I feel so confident it is deep meditation - my breath. Usually during the deeper levels of meditation I notice three breathing patterns I associate with different deep meditation experiences. Those are not in a sequence or according to scale, I just list them.

Pattern1: somewhat slower and deeper breathing than light meditation
Pattern2: such a slow breath not so deep as Pattern1, that often gets me wonder how I can even get enough oxigen, this is my most relaxed yet alert lightweight state
Pattern3: a temporary breath shifting, where I actually feel like something is forcing me to inhale deeper, and my breathing speeds up by itself, this is when the room tries to shut down ( this breathing gets me more agitated not the other way around)

That really got me thinking about a possible pet project that you could also try if you are interested. Trying to record breathing patterns during sleep to see if you can pinpoint delta. I would also like to compare sleep breath with meditation breath for myself. Now all I have to do is find a good recorder, and hope this works.
