hey Danelmon , welcome , sounds like you had just a taste of whats to come. You have to love that clear state of mind it can bring.
I know that during my first time I concentrated on my breathing too, so much that my whole trip also became about the breathing and I think that kept me grounded and I was unable to really fly. as I recall, my breathing sounded like it would start, then stop, then start , then stop,..which I know it does really, but this was in mid breath, like TIME was stopping, then starting, then stopping, ect ect..
I agree also, eyes closed was a must , no choice there! , BUT BOY did I see visuals. Rainbow colored linear wavy walls of pure love
If you care to hear my advice , I think listening to the music and concentrating so much on breathing I would try to skip next time, go in with a clear head and think of NOTHING, when random thoughts come in, replace them with NOTHING. literally think of nothing.
that seemed to help me reach higher ground.
and also, try the Changa, it makes it MUCH MUCH MUCH easier to get there.
Bring us back some good stories from your next travels
