I've managed to get myself into meditative and then trance states fairly quickly following MAP. But I've run into a strange spot lately: my breathing hits a point where it feels heavy and somehow my lungs and point of breath feel "below" me, if that makes sense. It's as if I've gone into sleep mode physically, but I get a sensation as if I'm not getting enough oxygen, which pops my mind up and back out of the trance state as I try to control the flow of air in.

I thought perhaps I was having apnea, so I adjusted my resting angle, getting to 35 degrees or a bit more, but the same thing happens. I think all my pipes are open. Is this common, or better yet, what have others found helpful in this situation?

Thank you...
