Back in the late 18th and early 19th century, a German doctor named FRANZ MESMER had a far out theory about energy transference between animate and inanimate objects. He called it "animal magnetism."
A Scottish doctor named JAMES BAIRD developed the idea and called it "nervous sleep" or "neuro-hypnotism," and later just "hypnosis." The word comes from the Greek hypnos for "sleep" and osis "to put to sleep."
These days, thanks to the American Psychological Association, we have a formal definition of hypnosis as "a state of consciousness created by 'hypnotic induction' and characterized by relaxation, focused attention and increased suggestibility, with alterations in perception, sensation, emotion, thought or behavior." Others define it as psychological regression, dissociation, or an altered state of functioning.
However you define it, hypnosis has a lot in common with ambient music, which also creates a relaxed state with focused attention. Whether it causes increased suggestibility and altered perception...well, that's up to you.
