Katathym imaginative psychotherapy (K.I.P.), knowing as well as Symbol-drama is one of the directions of modern psychoanalytical psychotherapies, using mainly the guided imagery and specific techniques based on different symbols named motives, all of them being accessed in reverie state (daydream). K.I.P. was founded and developed by the German psychotherapist and Professor Hanscarl Leuner in the middle of XXth century, representing the main work of his life. K.I.P. is a psychodynamic therapy based on classic and modern psychoanalytical theories related to human psychic structure and functionality, his/her development and ways of establishing/initiating relations, archetype and collective consciousness theories by K. G. Jung, method of active imagery, etc. The psychotherapeutic spectrum of this method is focused on revealing unconscious conflicts, as well as expands in the fields of satisfying archaic needs and creative development. By exploring and facilitating the client’s experiences, the method has a deep psychotherapeutic effect. Thus, the given work is focused on the stages of development of Katathym imaginative psychotherapy starting with experiments and observations, research of Hanscarl Leuner and concluding with its position nowadays, its applicability in different countries, as well as the perspectives of development of the therapy under discussion.
