After using an induction, be it the Dave Elman induction or others, it is useful to stabilize and deepen the hypnotic state of the subject. It is even necessary for quick and flash inductions.
We use this to ensure that your subject enters and remains in a stable somnambulistic state. On the other hand, to reinforce (deepen) the trance state if necessary. For example, if you want to lead your subject into the Esdaile state and/or “higher levels” of hypnosis.
Here you will find a list of the possibilities. You can use almost anything as a deepening technique, provided you announce it to your subject. Some of the techniques listed have the effect even without announcement.
