1. a state marked by greatly narrowed awareness and reactivity to a stimulus. 2. a state elicited by hypnosis or auto-suggestion and marked by openness, or accessibility, to suggestion. The hypnotized individual might experience a light trance, succumbing to such suggestions as being unable of opening their eyes or rigidity or absence of feeling in a limb; or a medium trance, wherein there may be post-hypnotic suggestion, posthypnotic amnesia, and partial amnesia. A deep trance may be marked by such impacts as being unable of opening the eyes without impacting the trance, positive and negative posthypnotic hallucinations complete somnambulism, and hyperesthesia.

TRANCE: "A trance is often referred to as a hypnotic trance, even though all trances are not hypnotic in nature."
