"Psychotic disorganization" is a territorial instinct affecting the selection of ideas within the brain. Humans uniquely have the ability to form and store very advanced ideas. This ability can be modelled with the concept of memes and memetics, that ideas are a second replicator in evolution, after genes, and can be understood as "imitation genes" or "mimicry genes", memes. When an animal is dominated territorially, their instincts allow them to break and submit. This is analogous to domestication, except within the same species (and not like for humans when the human species breaks an individual from the horse species. ) Central to the expulsion from a territory, is that the old territory no longer exists. And, that the individual has to submit to the individual or group who dominated them. The brain, evolutionarily, has evolved to abandon the old territory (at the level of memory), and does this by increasing activity in the mesolimbic dopamine pathway. For non-human animals, that lack the advanced memetic system that the human brain has (they are for example unable to think-up and produce a computer), this memory reset is things like olfactory memory (deeply tied to territorial mapping), but in humans it is also belief.
In Psychiatric mythology (Psychiatry is not a science, it is a false modelling of cause and effect that has evolved because of pecking order bias in the human brain of those who pushed the model), the person who has been broken, is labelled as "being in another reality". What this actually just means, is that they were expelled from the territory. Their peers, who choose to not recognize the social ostrasization, agree on a dogmatic myth that the individual they ostrasized "is in another reality".
Central to the pseudo-science Psychiatry, is that all "psychiatric disorders" are human executive function reacting to coercion from other humans, a cause and effect that is not acknowledged by Psychiatric mythology. The "social defeat response" for example, that includes what Psychiatry calls "psychosis", can not exist in a society of equals, it can only exist in a society built on a master-slave caste organization. The labels Psychiatry deals in, provides a myth that lets people socially abandon friends and family in need, throwing them under the bus, while pretending to be "helping" them. The mythology provided by Psychiatry makes it socially acceptable to sell out your close ones so that you can exploit it to climb a social dominance hierarchy.
