Trance:
Where imagination and emotion come together. There is a connection between great sex and trance. If you think about it, great sex is a trance, an erotic, sensual trance.
There are similarities between trance (hypnosis) and pleasurable, satisfying sex. Effective hypnosis is intense focus and concentration and a strong response to suggestion. When a sexual experience is at its best, there is also intense focus, concentration and a strong response to suggestion as well as stimulation.
The big "O" or Orgasm maybe the ultimate trance. In both an orgasm and trance, profoundly strong mind/body and spiritual self makes connections and sensations that are concentrated to the point where all other thought, emotion, feelings and sensations cease to exist from the mind/body. An orgasm is it's very own state of mind/being.
Sexuality & Hypnosis:
Hypnosis is a beautiful way for two consenting adults to explore and enhance their level of intimacy as well as the intensity of their sexual relationship.
There's evidence supporting the theory that both sexuality and hypnosis are derived from the same biological substrate for social intimacy. That waking and hypnotic suggestion works because it makes use of the higher human capacity to synchronize our body rhythms in intimate communication, which is, a highly receptive and cooperative process.
The evidence for it is based, in part, upon the comparison of physical responses to hypnotic suggestion, with our visceral responses to poetry/music. (which is rhythm and words that compel us to feel or imagine), this is how rapport develops in hypnosis compared to other intimate communications. The underlying processes that help us synchronize with each other in sexual intimacy are present in creating hypnotic rapport, thus the same/similar factors lighten/deepen both forms of rapport.
