Teacher gets to practice her techniques on herself.
Today, I used "The Hidden Observer" today while having oral surgery. There was an area where the local was not working so I went deeper into hypnosis and just "observed" the suturing. Worked like a charm !!
The phenomenon I refer to can be found in:
