Hello and welcome, and please forgive me — I was just teasing. I haven't literally "been there" as distinctly as I made it sound. I said that as a goof, and to stimulate discussion. In all seriousness your experience sounds fascinating, and I have been there in some vague sense; at the very least I can say I've met a giant or two.

I certainly can relate to the feeling of "superconductivity" on the comedown.  I  know somebody who calls it kundalini. It's as if my body is a wire and a huge torrent of energy is flowing through me.

About validation between multiple travelers: that's a sticky issue. What exactly would constitute proof of anything? I mean, to a diehard skeptic, even if two people drew almost identical pictures of what they saw, it could be attributed to social programming and shared archetypes.

BTW, the Hyperspace Lexicon document is wonderful at describing many of these archetypes and "areas" of hyperspace Hyperspace lexicon - DMT-Nexus Wiki
