Schizophrenia is an ancient mystic trapped in a modern world without the security or safety box of belief. Insanity is pushing the link into beyond, floating beyond reality to touch the face of god. Spirituality when denied creates rifts in the thought processes, gumming up the flow of information to transform a unique ability into a problem.
Schizophrenics build the surrounding environment into their mindset as opposed to the reverse, their subconscious builds into their conscious before it hits the outside world, mentally constructing the universe as it should be and then intaking what it is. Problems occur as desire born perceptions form alongside the true ones, in the schizophrenics brain the collective reality can be lost denying it from the stability it provides but providing an oppurtunity to be truly unique.
The "hallucinations" occur when the shifts in conscioussness the schizophrenic experiences come to the forefront, images and voices can appear as well as mis-perceived objects, reflections of thought processes in the gap. On a greater level this affects the ability to interact, as this shading of perception influences every aspect of the schizophrenics life, every intake of information from the out and every sense of self it has within.
Due to these illusions being constructed from deeply imbedded subliminal thought processes and hidden emotions, they can appear in the format of a higher being/world/level of intelligence, leading the schizophrenic to cling to these illusions as proof of his/her holiness or special powers, a higher calling/purpose. S/he will believe in the illusions as a different format of truth and will struggle to align the person into a framework where the illusion can mix successfully with reality. Mystics are at a supreme advantage here, as they generally have a clearly defined path to provide self-confidence and belief they are good, the schizophrenic is merely "possessed" and the mystical flow is percieved as demonic, leading to inner fight and lack of belief in self cycling with an over-imposed ego to compensate. Belief hardens the synaptic passageways, the mystic has the schizophrenic link hardened as per his/her format and therefore can leave it to recognize the real world. The schizophrenic is trapped in the perpetual battle, never willing to give in to the thought processes it percieves as corrupt and unable to delete them, instead of a stabilized spectrum it varies through the extremes on pretty much every aspect of self. Psychosis overtakes when denial has reached such a point it contradicts itself or hard reality, forcing focus unto the other end. Denial obstructs the thought lines leading to incoherent information processing and therefore interaction.
To finish off, consider the power of one who will have a fully interlinked sub-conscious and conscious to have a pure state of being in total awareness. Could Moses not of been a schizophrenic individual with belief fortified by his supporters to have it fully complete the circuits of self guided with perceptions of holiness to literally ascend above the realm of man to connect with the higher intelligence of creation, his own inner self without the conflictions of existance to have a pure state of being unconstrained by a sense of self....
