I mean that I think it's likely that lots more people experience varying levels of psychosis, than anyone realizes. Probably a lot of poor decisions are made due to mild psychosis. Mine began more than a year before it became really bad, and it started as basically normal but slightly magical thinking. Belief in 'the universe', signs and symbols, that sort of thing. I made a lot of poor decisions that year, due to the psychosis. But from the outside it would have been impossible for anyone to tell it was developing, it was so mild, and my thoughts and behaviors appeared basically normal. It was a very gradual detachment from reality, from specific actions having specific consequences.
(It did eventually turn full-blown - psychotic breaks, the whole lot.)
