Among the tight knit group of friends that I had the majority of my psychedelic experiences with, we dubbed that 4 hour period after the peak as "Cranky Religion." It's when you've reached a point where you feel enlightened but too tired to give a damn. You mostly sit around and relate to one another how messed up society is.

Given how personal and intense my experiences were for both how I relate to myself and the world, but also with my relationship with my best friends, I can't imagine really doing LSD or Mushrooms in a rave/party like environment.
