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.
I saw exactly the same infinite arms thing with zero prior interest in religion. It took me to place “I was once before and should know well” other entities protested because why bother when he needs to go back soon. Then I came back to my room and had no idea what to do with that experience.
