You are totally right, psychosis is seldom mindless gibberish. That isn’t even the case with hard brain damage, there most probably will only be things (capabilities or experiences) removed or added, which by themself still would “make sense” in some way or another! I also think the brain might be of a different nature than our technology, more stable and robust in operation, not like a jpeg where you hack some bytes and it would become broken noise. Psychosis is more like - dreamlike states augmenting or blocking the normal consciousnes. Strange soulless voices of many kinds, additional thoughts and irrational beliefs while your ability to reflect it is weakened at the same time. Thought becomes narrow, and the borders between consideration, contemplation, and stubborn belief can become fluid. Random occasions of drug like hallucinations, but like in a more sober state, or experiences like communicating with spiritual beings, feel totally wired, like controlled from external, have strong religious experiences and vision, etc. I believe people who wrote the Bible, or Buddha, they did not lie - they were just trying to describe what they were experiencing. It is like kind of like bad trips on LSD or Mescaline. The real bad side is it can make you belief strange things, also dangerous things about people who will have no clue what you are about when you account to it. There will almost always be kind of “islands of clarity” within the experiences, where the psychotic individual will come back to sanity for a while, being able to reflect the state or just forget it for a short while. I well…only came into contact with psychiatrists when my head exploded badly many years ago. Treatment is medication that in high dosage will dull out the mind, make you very depressive and weaken the experiences or even totally stop it, but it seems it is not always effective. It is also very unhealthy stuff, damaging the brain on the long run.
There are alternative concepts like Soteria, Windhorse etc. who seek to aid people get through their trips in a guided way and with minimal medication. Average to large (intoxicating) cannabis dosage (or other drugs and also alcohol, but each in different ways) might let sick stuff bloom up, while constant THC microdosing and especially pure CBD in high dose can weaken the experience and make it easier to handle. It is said potheads often get psychotic, and can recover by stopping to smoke hardcore.
If you wish to learn what is possible, read psychosis accounts from people on the net. Or alternatively reports from people using dissociative drugs like DMT or PCP, but still those are different states. There seem to be different levels of what is possible to experience. The experieces follow similar form, though they incorporate your personal knowledge - like 500 year ago people would rant about witches (and burn innocent), nowadays the talk is about aliens or chip in the head, what you describe might be the next lvl. I’ve just had a real hard trip about magical plots etc., but it is currently fading. All the interrogation stuff etc. is classical psychosis stuff, it can confront you with anything you know about and what is possible with phantasy. I could imagine that people might try to use similar forms of experiences on people to fuk with them badly or trigger psychotic states, but I think it is for real that the human mind can also produce it without any tech involved an all by itself. Research what happens to humans if deprived from sensory input for extended periods, and it has always been like that and is most probably also the case for most animals.
Psychosis also shows you deeply all your fears and will confront you with them. Even the silliest, or ones that you not have known about yet. That is maybe where soteria people etc. try to lever the mind back, by conquering the fears, you might gradually conquer the delusions.
I do not believe people are being driven crazy with tech into fake psychosis, but who knows. If the brain was understood well enough, robotics would already be on much higher level, and it is easier to build a robot to deal with stuff instead of trying to drive organic beings into it artificially. Or just bribe some spineless thug. I do agree however on your idea of media manipulation, in that it seems a cultural thing going on worldwide driving people into images of hard competition and ego-dominated states of minds. I take it as a symptom of over-population that was failed to be dealt with for too long for whatever reason. Sad stuff.
And yes a strong psychosis is just about the worst mindfuck one could ever imagine. The sort of stuff that bad guys only dare to dream about to be capable themselves, but could never be attained by human capabilities. Yet still, unlike those would, it will strangely always leave some room and chances for yourself to try to handle it and maintain yourself. It either destroys you, or makes you something beyond any understanding that you had before the experience.
Take care for yourself if you think you experience such states. Best thing to do to recover, is keep all stress and sorrow as far away as possible while it is burning, stay away from the things that were exciting your states for a while, live healthy with physical work or excercise, be in protected, safe and easy environment, have people to talk to and who watch for you, sleep enough or even more then nessicary, use sleeping medication if you can’t properly sleep. Some people also just regard their psychotic experiences as kind of spiritual experiences or awakenings, and the suffering is just part of overcoming it in a later stage. Also take note that psychotic people who are weak in managing their state might be regarded as easy victims for certain people, for whatever purposes. So rather the other way round than you thing, not psychosis to control people, but rather, trying to wire up and abuse people who are already psychotic.
