As someone who experienced psychosis via a legally prescribed medication (adverse reaction), I can tell you that we just may be a lot more than we realize.
In psychosis, the visions and voices (not hallucinations*) are extremely compelling. The psychotic world is a fascinating and frightening place. I learned many things about myself and the construct while in the full-blown state.
I can honestly say that it permanently changed my view of our existence and our purpose in this world and that I am still on the fringes of that psychotic plane. I still hear the voices. I still receive "the feed".
Medication moderates my experience, but I confess that the intellectual journey through psychosis was so rich that, despite the terrible fear I felt, I find myself wanting to return.
I know where we can go. I've been there myself. When I "got back" I wrote it all down and I'm still writing four years later.
One of the biggest insights I had in the psychotic state was that our brain potential is off the scale, but for some reason our sensory array, the brain structure that actually processes the data, is not equipped to handle all the input.
In the psychotic state you perceive and analyze much more data. Emotionally, homo sapiens are not ready for that level of information processing. We are easily overwhelmed. That's when the white coats or the badges show up.
I was taking so much data onboard I was having chest pain from the stress of processing it.
I firmly believe we have to potential to be mini-"gods" of a sort. Not in the vein of God with a capital "G" by any means, but intellectually stellar with extremely heightened senses. We see shades of this state in savants, synesthetes and, of course, in people like Albert Einstein.
My experience taught me either that man is meant to be more than he is, or he was, at one time, closer to being a "god" than he is now. These may be the men who built the pyramids and who laid the foundations of our civilization.
We shouldn't doubt ourselves and we shouldn't limit our horizons. The potential is there. We need only find a way to tap it without descending into madness.
I did find myself wondering if insanity was God's method of ejecting us from the Garden, paradise. It certainly seemed to be. I was profoundly unhappy in psychosis, frightened of everything, vulnerable to any attack. I did sense the devil's hand in it. We are surrounded and don't even know it.
*In psychosis, everyday discussion is interpreted differently than it normally is and visual input is largely interpreted as symbolism. Everything has multiple meanings and you spend the bulk of your time deciphering the meaning of it all. It is exhausting.
