This conundrum – does hypnosis have a real, physical basis, or not? Important shifts were happening elsewhere, however. First of all, the centre of hypnotic gravity moved from Europe to America, where all the most significant breakthroughs of the 20th century took place.

Secondly, hypnosis became a popular phenomenon, something that was increasingly available to the layman, outside of the laboratory or clinic.

At the same time, the nature of “ordinary” consciousness is better understood as a series of trance states that we go into and out of all the time.

The history of hypnosis, then, is like the search for something that was in plain view all along, and we can now see it for what it is – a universal phenomenon that’s an inextricable part of being human.

Mesmer was also the first to develop a consistent method for hypnosis, which was passed on to and developed by his followers. Mesmer himself, for instance, liked to perform mass inductions by having his patients linked together by a rope, along which his “animal magnetism” could pass.

He was also fond of dressing up in a cloak and playing ethereal music on the glass harmonica whilst this was happening.
