I've had "challenging moments" during trips. And I think they were a learning experience. I have never had a "bad trip".

I do not know how to explain it - but I know from my experiences that a truly bad trip wouldn't remotely compare. I'm very convinced a bad trip can give you real PTSD.

I'm glad your experiences weren't worse. I don't mean to minimize your experience. But I think it can unimaginably worse.
