I did it once. Felt like my consciousness rocketed "up" out of my body, but not up through physical space, through some 'adjacent' space. Then I saw/felt "infinity". There was no time, and I saw a hundu-esque god/goddess with infinite arms. I had no interest in eastern religion prior. Not disinterested either. I just didn't think about it, the way I don't think about golf.
It was a neat thing to experience.
