This is not true, in my experience. The best way I can describe shrooms is “they show you what you need to see at that moment in your life,” and sometimes the “bad trip” is exactly what the doctor ordered. I have literally only ever seen “bad trips” be useful and transformative for people.

I do agree that you shouldn’t ascribe too much weight to certain things, but personally I’d say this is applicable more to specific spiritual conclusions, “seeing god,” etc. No, you didn’t see god, you were taking a hallucinogen and were high as balls.
