For everyone who has an experience like you, there's someone like this guy: https://www.ecstaticintegration.org/p/dmt-derealization-and-...

Anyway, since you were dancing, I assume you used MDMA which is much "less psychedelic" than acid or DMT (and much more of a stimulant). There's also more potential for misuse and addiction. Ketamine, too, turns out to be quite addictive by the way.

It seems clear that psychedelics are going mainstream and, unlike the 60s and 70s, they will be legal in some places. I'm not convinced that ths will be a net good, partly because it's not clear that it was a net good in the 60s and 70s, but we'll see.
