My Yoga Teacher Now a Hypnotherapist

My yoga teacher has now become a hypnotherapist. Our sessions are filled with suggestions of being happy, peaceful, and healed. We imagine blue or violet light entering our bodies healing certain thing in our bodies that need healing. It was undetectable of what was going on in the session. She told us 2 weeks before that she got certified as a hypnotherapist. All of the rest of the class did not have any idea of what was going on.
