Gateway Process
“Gateway Process” is a technique that can be used to escape the restrictions of time and space.
The following 1983 document was declassified in 2003: Analysis and Assessment of Gateway Process
“most if not all people reputedly go into an out-of-body state during REM sleep”
Hypnosis
...the left side of the brain screens incoming stimuli, categorizing, assessing and assigning meaning to everything through self-cognitive, verbal, and linear reasoning.The left hemisphere then dishes the carefully prepared data to the non-critical, holistic, pattern-oriented right hemisphere, which accepts everything without question.
Hypnosis works by putting the left side to sleep, or at least distracting it long enough to allow incoming data directly, unchallenged entry to the right hemisphere.
There, stimuli can reach the sensor and motor cortices of the right brain, which corresponds to points in the body. Suggestions then can send electrical signals from the brain to certain parts of the body.
Directing these signals appropriately, according to the report, can elicit reactions ranging from left leg numbness to feelings of happiness. Same goes for increased powers of concentration.
Transcendental meditation
Through concentration the subject draws energy up the spinal cord, resulting in acoustical waves that run through the cerebral ventricles, to the right hemisphere, where they stimulate the cerebral cortex, run along the homunculus and then to the body.The waves are the altered rhythm of heart sounds, which create sympathetic vibrations in the walls of the fluid-filled cavities of the brain’s ventricles.
He observed that the symptoms begin in the left side of the body, confirming the right brain’s complicity. Bentov also states that the same effect might be achieved by prolonged exposure to 4 - 7 Hertz/second acoustical vibrations.
