“18. Time-space Dimension: Up to this point our discussion of the gateway process has been relatively simple and easy to follow.”
I literally laughed out loud at that.
But so ok, the CIA investigated literally any potential way to spy on the soviets and loved the idea of astral projecting operatives into enemy bases, or psychic links for instant communication. Either it was all a failure and never resulted in anything or there is right now an operative beaming psychic thoughts into my brain causing me to dismiss their existence... depending on who you ask.
There’s a lot of now outdated concepts, the whole right brain, left brain thing is something many would love to move away from, but it’s just outright confused about brain frequencies. At one point it was conjectured that mental states were brought on by the EM frequencies produced by the brain and thus if you got the brain to a certain beat, you would induce an experience. Like how when you want to replay a game on your computer you just capture the clock speed of your processor and induce that speed to restart the game.
“The gateway tape”
Ok, that’s what I was looking for! it had to be that or drugs! My guess is the gateway tape is a binaural beats tape. You can find and play with this concept online or in many apps. The idea is that a slightly different tone is played in each ear and the brain combines them to produce a beat equal to the phase difference, which the hypothesis being that producing a phase difference similar to sleeping states will cause the brain to follow.
Flicker lamps are a visual version of this and in part where this all comes from. You might not be able to boot up your favorite game through inducing similar frequencies but you can sure create a nice feedback loop. At just the right frequencies combined with a calm resting state a flicker lamp can prime the visual cortex to hallucinate patterns to occasionally full dream like experiences. (It’s hypothesized that ‘visions in the campfire’ experiences are accidental versions of this.)
The rest is a lot of trying to come up with ways to align his hallucinations with reality, as if they weren’t just naturally induced hallucinations.
