Psychoanalytical Therapy is a method of "talk therapy" which aims to bring subconscious or repressed experiences and feelings to the surface to be examined and discussed.
There are many techniques a therapist might use in a psychoanalytical approach, such as word association, dream interpretation, and transference analysis, wherein your therapist will help you to spot trends in your current relationships that may be carrying over from negative childhood experiences.
A positive therapeutic relationship is a crucial part of psychoanalytical therapy as resistance is an extremely common reaction to experiencing these repressed memories. By utilizing the techniques your therapist gives you and working closely with them to analyze your past experiences, you will begin to release repressed memories and healing can begin.
