Chönyid bardo at the pool

I was swiming at The Aztec's pool and suddenly came to me a thought of testing Chönyid bardo, I just waited in the 2m pool untill there was no one in the pool so i couldn't be disturbed (as well as seen weird :) )because I just Layed face-up and started breathing, it was really weird because there was one moment when i didn't feel the water, I was extremely relaxed that when I "woke up" I was UNDER THE WATER! i didn't feel that i was really drowning, the worse part was that i was in the 2m pool so i just managed to get to the edge and breathe again.

I also counted the time that it took me to relax (and wake up) and it really was a short period, 3 minutes, in those 3 minutes, I (as I said) didn't feel the water, like flying, coming to the end of those minutes I started loosing sense of location and i didn't feel my legs or arms anymore, (probably because I wasn't breathing)

total calmness, EXTREME! I reccomend it afer a good portion of exercise, but with supervision :S
