The fact that you actually believe this makes me believe you're pretty much a sperglord who thinks his narrow range of experiences explains the entire cosmos.

Saying that psychiatric disorders are "not real" makes you just as stupid as the people who insist that those same disorders can be cured through praying to Jesus.

And past lives don't count for your experiences. Those are not YOUR experiences. Plus, there has never been any empirical scientific evidence to support past lives beyond some aging hippy claiming to have been famous people.

Which is what past lives always are. Famous people. Important people. Or just people who did things.
