I had a similar experience. Saw the same thing, so I believe you without even having to look it up. Floating on a fluff of clouds, with a rainbow following him around and what seemed like an infinite amount of angels surrounding him. Not a NDE. I had just finished repenting, with tears in my eyes, and ended up having a full-on closed-eye "hallucination" where he put his hand on my head and I instantly got a wave of what felt like static electricity all over my body. Almost felt like a positive mushroom trip, but I was stone cold sober. I went through a wormhole once, too, where I met God (or a really high ranking angel), who showed himself in the form of someone who almost looked like Leslie Nielsen. He evaluated my life so far, and said I was doing okay but still had some work to do. As I was waking up, a voice in my head said, "you're welcome back anytime. That comes straight from the top."

Nobody can convince me God isn't real. Even if you were to tie me to a post and feed me to the lions. I just have a lot of sin-deprogramming left to iron out. Will get there. Undoing a lifetime of blindness ain't quick or easy.
