About séances, trances & altered state of consciousness cont'd:
The research indicates that information enters our brains minutely, hourly, daily at the conscious and unconscious level. Some of the unconscious information never makes its way to the conscious mind for active processing but remains in our subconscious - hypnosis has proven to be an effective method in accessing/uncovering information buried in a person's subconscious.
There is always background activity taking place in our brains when we are awake and asleep and there is also a constant interplay between the conscious and subconscious mind - some information from the unconscious mind makes its way to the conscious mind for active processing and vice versa - issues from the conscious mind can get pushed out of consciousness into the unconscious mind.
Our minds are never perfectly still. There is always subtle processing going on in which we can't consciously identify the thoughts in terms of clear words or clear images. There are rapid and fleeting associations taking place in the subconscious mind. Subtle processing or preconscious or subconscious processing gives rise to conscious self-talking and imaging, but as I have already stated, not all unconscious information makes its way to the conscious mind for active processing some remains in our subconscious and can be accessed/uncovered by methods like hypnosis.
Psychologists, neuroscientists etc. have observed that there are certain intense practices which can alter a person's mind or state of consciousness to the point where, the person descends to deeper levels of his/her consciousness and releases from the deep mind, thoughts, impressions, visions, images, voices, words, etc.
This altered state of consciousness involves a transition from the left brain to the right brain wherein the rational left brain is suppressed and quieted and the perceptive faculties of the intuitive right brain are awakened and the person transcends to the unknown, inner world of their subconscious mind.
This opens the way to the unlocking of a deep level of consciousness where psychic and extrasensory perception can be done and so some persons may become psychic or clairvoyant being able to forsee the future when in fact it is thoughts, impressions, images, visions, voices, words etc emerging from the deep, intuitive levels of the right brain as their own subconscious mind begins to "speak" to them. New insights well up directly from the fluid matrix of the subconscious and the subtle processing taking place there, without having to be first processed at the conscious level. Some persons become psychotic or hallucinatory or some persons become both psychic/clairvoyant and psychotic/hallucinatory.
Psychologists, neuroscientists etc. have observed that in some persons, intense spiritual practices like intense/strong/deep praying, meditation, fasting etc. result in a self-induced altered state of consciousness and attendant suppression of the rational left brain with the unleashing of the subconscious as I have described.
