Read this article about a group of Scandinavian scientists who have been studying the hypnotic state. The scientists observed some highly hypnostisable individuals who showed a particular glared gaze and specific motor and perception experiences in the hypnotic state. After this research, the team of scientists concluded that the hypnotic state can be identified as a particular state of consciousness different from our normal state of awareness- or waking state.
Most people find it easier to access a deep state of relaxation and concentration if they close their eyes, thus blocking any visual stimulation and allowing this way a clearer exploration of their inner world. This does not allow for most of the cases the observation of such glazed vision. However hypnosis can also be achieved with open eyes specially if a subject is highly hypnotisable.
