Just weighing in, but sampling for these events isn't necessarily applicable to the general population.

Whether that's because people whose brains are more likely to experience psychosis are more drawn to music festivals, whether it's a supply-trust or dosage issue (lower purity or higher potency compounds, goers don't know what they took or how much), or that prior exposure to cultural lore like "drugs makes people want to fly" is influencing them, I don't know.

Age is also a known factor - schizophrenia is more likely to emerge around the age of maturity, often associated with stress and drug use (again, may be wet roads causing rain - people self-medicate even if they don't realize it), even though, statistically, "college" would be just as likely, and it often happens as a psychotic break, the way you described. I worked with young musicians for many years and saw it happen regularly enough - no psychedelics required.

So the fact that everything you mention happens is evidence, but of what? That's a harder question to answer.
