You know, just a random remark here... I remember once saying to my psychiatrist that having had psychosis, it gave me a profound respect for just how powerful the brain was, being able to create complex hallucinations & delusions...

He then said "the brain doesn't create it, it's just the brain processing real information the wrong way"

... it's almost strange to think, a few faulty connections & suddenly all this information gets processed to mean something completely different to what it should.
