I have written a couple of posts on 'visual weirdness', I would like to post another update in case someone else is experiencing the same symptoms.
I have PCS after a bang to the back of the head in an RTA. I have a very strong visual element to my condition.
I have had optometry treatment, coloured lenses, to correct moving visual patterns (pattern glare), horizontal line movement and fluorescing colours in daylight. It has worked after a year.
The lenses do not work in LED or fluorescent lights. It seems that this is a completely different type of light sensitivity altogether. It causes my body to go into a state of physical panic ending in a fainting episode, this is the sympathetic response and is controlled by the brain. I am currently trying to approach it with an allergy method of treatment. Limited exposure over periods of time etc. I can get 55 minutes now before fainting compared to 20 minutes a few months ago. I am lucky to have been screened by a specialist in Gobowen Hospital who have come up with a plan for when I have hospital treatment, basically I don't queue, as soon as I arrive I'm seen by the doctor. If I am going to stay for more than half an hour I am sedated. This now seems to be the norm in any hospital environment, there's a note in my records. This is something others should try to get if they have trouble with lighting.
Now for the main topic, the hypnagogic state. The place between the conscious and unconscious dream state. This is internal visual rather than external as mentioned above, there is no connection. It seems that it has nothing to do directly with vision at all but with brain chemistry instead.
My first experience was the feeling that the front of my head was full of lead and I was pulled into a dark tunnel with yellow plasma clouds dragging me into a tunnel to be pushed into a pure black eternal space with geometric patterns and stunning colours. I thought I had just died and felt happy with the experience, so there is another side after all. It was a feeling of pure elation.
This happened multiple times a day for months with a different experience each time.
It went away after six months or so and reappeared during a meditation session over a year later, after being told to practice by my neuro-psychologist. I mentioned the experience had returned during meditation but for some reason she would not talk about it. Why??
I have been trying to learn what this experience is ever since. It is described, the same state, in many different areas.
Carl Jung vividly describes it in his work 'The Red Book'.
It is called psychosis in psychiatry
It is called Kundalini in meditative yogic practice.
It is called the astral plane by the occultists.
DMT users describe the same condition.
It is also thought to be a sleep disorder.
So what is going on, all the descriptions are the same in essence. The similarities are that the frontal cortex, the logical filter, is shut down to varying degrees. There are varying states of sleep paralysis of the body, some describe there is no body anymore only consciousness. Areas of the brain other than the frontal cortex become hyper producing visual and other experiences.
Brain scans from people in a state of REM sleep, meditative trance, psychosis, psilocybin and LSD dose and DMT use show very similar patterns.
The dream state is thought to be when your brain is repairing damage and sorting information. The states above are the experiencing of the unconscious dream state while still conscious to varying degrees.
The connection here is that brain chemistry molecules such as melatonin involved in sleep regulation, seratonin good feeling, psilocybin and DMT and many others are all tryptamine molecules with different side chains. They compete for the same sites on receptors in the brain producing similar effects.
It's fascinating that currently psilocybin (magic mushrooms) and DMT are being used to help change the behaviour of chronic depressants and alcohol users among others. They are basically rewiring the neurons via trippy chemicals.
This gets me thinking that there is scope here for some kind of treatment to speed up or repair brain damage or brain function.
Mindfulness based cognitive therapy is big where I live and I am starting a course next week. I think meditative practice helps stimulate tryptamine molecules in the brain that enables the repair or generation of new neural pathways as I describe above. Mindfulness is the shutting down of most of your thought and the concentration of a specific thought or action that needs to be addressed and enables behaviour change.
I will let you know how it goes and if there is an improvement or not.
I would love to hear any comments from people thinking anything similar.
