Hypnotism

In medical jurisprudence. A psychic or mental state rendering the patient susceptible to suggestion at the will of another. The hypnotic state is an abnormal condition of the mind and senses, in the nature of trance, artificial catalepsy, or somnambulism, induced in one person by another, by concentration of the attention, a strong effort of volition, and perhaps the exercise of a telepathic power not as yet fully understood, or by mental suggestion, in which condition the mental processes of the subject and to a great extent his will are subjugated and directed by those of the operator.
