I've been thinking about how to understand trance. I've heard we enter trance regularly throughout the day, but in my experience, it might be better said that we're always in trance, but if that's true, that's essentially like saying we're never in trance.
After some brainstorming and paying attention to how I fall asleep, though, I get the sense that there are different "channels" of awareness, and that trance is one of these channels. Right now, I am aware of about four separate channels:
* Experience: This is our senses detecting the outside world. Our sight, hearing, etc. We don't have direct control over this, it's all the environment acting on us.
* Imagination: This is conscious, directed creation of sensations internally. Thinking of a lemon, and all that. It does not result in experiences, as we remain aware that it is internally generated.
* Limbic: This is emotions, how we feel about things. Experiences can lead to emotional ties to things, which leads to imagination that might not be conscious and directed. This is how things we particularly enjoy or worry about can keep cropping up, even if it's not experienced and not directly imagined. This is the first of the more subconscious forms of awareness.
* Trance: This is internal, not conscious, not directed, and not tied to emotion. Maybe it's related to the inherent imperfections in the senses, like visual snow. But it's like how you're in bed, trying to fall asleep, and your mind drift to interact with things and people that aren't there. This is where your dreams come from in sleep, and although it's often completely ignored during wakefulness, it's all still there. Once again, though, these don't appear like experiences. It would only be hallucination if you're having trouble identifying which channel is which.
From what I've read and experienced, hypnosis involves finding a way to blur the boundary between experience and imagination, perhaps through blurring that with trance. Is this what the experience is like for you? Perhaps it sounds like I've been going into too much detail and splitting hairs, but many inductions seem to involve blurring imagination and experience, even though they're distinct.
(I'm approaching this from being interested in learning more about hypnosis, but having no idea what's being attempted, because I've had no success in being a subject.)
