Countertransference was first mentioned by Sigmund Freud in 1910. The process of countertransference is a concept of psychoanalysis. Initially, countertransference was understood as a disturbing influence on the unconscious feelings of a doctor or therapist, which hinders rather than benefits the treatment process. It obstructs the therapist's free view of the patient. Forty years later, with Heinemann as a pioneer, the countertransference was put in a different light and from then on was considered an appropriate instrument of psychoanalysis. The perception of countertransference opens up important diagnostic possibilities for the therapist, also in hypnosis. This involves emerging feelings, expectations and desires of the therapist, which he subconsciously directs towards the client. In psychotherapeutic terms, the therapist thereby leaves his neutral frame, which can be an obstacle to the therapy or a gain in which the transference is addressed. In hypnotherapy, subconscious needs and desires can be made conscious and given space. Thereby the view is directed to the important things.
