Trance is an altered state of consciousness. MRI scans have shown that, when in trance, your brain functions differently from normal waking, imagining, dreaming and sleeping states of consciousness. You have access to your subconscious mind.
There are many levels trance. The levels of trance that you can enter in deep meditation and hypnosis are essentially the same. Hypnosis is the West’s tradition of self-healing in trance, and meditation is the East’s tradition of self-healing in trance. ‘Hypnosis’ and ‘meditation’ are very broad terms. So opinions of comparisons differ. There are many hypnosis techniques and lineages just as there are many meditation techniques and lineages. They differ with intention, approach and experience but all share one understanding in common : Your subconscious mind is the most powerful part of your mind and you can effectively learn to use it and transform it in a state of trance.
