In the first part of this paper a short overview of the history of hypnotherapy and hypnoanalysis is given. Within the modality of hypnosis, the patient can make contact with his unconscious much faster than in the waking state. Primary process thinking and vivid imagery play a great role. Hypnotic imagery and the hypnotic state per se are “royal roads to the unconscious” on which the hypnoanalyst must attempt to walk with care but also with confidence, so that defenses are not pierced prematurely and the patient can learn to use to the fullest extent his innate healthy coping potential. The second part of the paper deals with the newest development in the field of hypnoanalysis, the treatment of the borderline patient with specialized hypnotic imagery techniques that have been found to help such patients overcome splitting, achieve object constancy, and good internalized object and self representations.
