Psychoanalysis focuses on revealing the unconscious forces that can rule a person's life. It is an intensive form of therapy that may involve 3 -5 sessions per week, and may take several years. Oftentimes, the client lies on a coach, and begins to speak about whatever comes to mind. Techniques such as free association are employed, where the therapist says a word or phrase, and the client responds with the first thing that comes to his mind. In doing so, the unconscious gradually reveals itself, through ways such as changes in vocal tone, "Freudian slips," through the way the client interacts with the analyst, and also through repeated patterning of the subject matter. Particular attention is paid to the normal developmental processes of the psyche and how these may have been interrupted; and to analyzing resistance that emerges during the therapy.
