Hypnosis refers to any method of inducing trance, which is a naturally occurring mind state that we all experience in its lightest forms many times a day. 

Absolutely, the weight of clinical evidence over the last century is indisputable. 

Nobody really knows for sure. There are many theories and models but perhaps one of the most widely quoted, and useful because of it’s simplicity, is the Mind Model.

Because hypnosis is essentially an agnostic tool, it’s not tethered to any single therapeutic philosophy. Hypnotherapy at it’s best can be a broad and versatile approach that allows the practitioner to draw from all other psychotherapeutic disciplines.

It’s generally accepted that anyone has the potential to experience hypnosis if they are willing and open. However it’s clear that people vary immensely in the way and degree that they respond to hypnosis.

This depends on 2 variables, how responsive the client is to hypnosis, and the complexity of the issue being dealt with.
