Classically, the bringing of unconscious thoughts and feelings to consciousness is brought about by encouraging a patient to talk about dreams and engage in free association, in which patients report their thoughts without reservation and make no attempt to concentrate while doing so. Another important element of psychoanalysis is transference, the process by which patients displace onto their analysts feelings and ideas which derive from previous figures in their lives. Transference was first seen as a regrettable phenomenon that interfered with the recovery of repressed memories and disturbed patients' objectivity, but by 1912, Freud had come to see it as an essential part of the therapeutic process.
