I don't think thats what he was tryin to say man, jus reality is only real for those who live in that reality, and reality is all in ure head, and we all got different heads, so why giv a shit about whether or not its in ure head or sumthing thats independent, because no1 has got a clue, and will never have a clue, so don't worry about it. As for psychosis, educate yourself on the history, diagnosis, prognosis and symptoms, and the methods of determining whether sum1 is mentally ill or not, then draw ure conclusions. My personal opinion is that it doesn't exist, and I'm sure if I told you all the reasons for why I think that, u'd still stay with ure opinion that it does cuz thats what ppl do...........god bless em.
