Many attendees were acting fairly happy/goofy but it's just one of those things that would be inappropriate to bring up or ask. I attended a follow-up 3 day advanced seminar to see if I could recapture that feeling and left disappointed.
This stuff falls under what I would consider the 'cult' umbrella and I think one of the reasons why such orgs are so successful is because group empathy sessions are really powerful. Unsure if my experience itself was in essence an MDMA flashback or if MDMA (and psilocybin) is a conduit to what group empathy can achieve.
