The British psychoanalyst Marion Milner’s (1900-1998) use of imaginative scenarios (both the patient’s and hers) is analyzed in an analytic situation - considered a metaphor of the parent-child relationship - in which the patient introjects the type of care of the therapist. The illusion of oneness, of the "me not-me" fusion, has a structuring function which may not take place during early childhood. The analysis allows patients to regress to their earliest experiences in order to work them through and either take up or go through a developmental process. Some aspects of theory and technique are considered, especially regarding the concepts of countertransference, concentration on the body, emptiness, doubt, frame, fusion, creativity, play, pre-logical thinking.
