Hypnosis is a trance state.
Trance or hypnosis in itself wont make those changes. This comes down to the skill of the psychotherapist.
Hypnotherapy is the psychotherapy that is used in the trance state. There are many styles or approaches of Hypnotherapy that may be used.
I am the founder of EMI Emotional Mind Integration. This is a powerful present day neuro-trance-psychotherapy that utilises all that has been developed before this tiem along with the latest knowledge in neuroscience into an elegant, efficient approach for resolving a wide range of issues.
The approach is designed to resolve or clear one neural pathway each session related to your issue.
This means a highly effective approach.
