The author notes that neuropsychological research has discovered the existence of two long‐term memory systems, namely declarative or explicit memory, which is conscious and autobiographical, and non‐declarative or implicit memory, which is neither conscious nor verbalisable. It is suggested that pre‐verbal and pre‐symbolic experience in the child's primary relations is stored in implicit memory, where it constitutes an unconscious nucleus of the self which is not repressed and which influences the person's affective, emotional, cognitive and sexual life even as an adult. In the analytic relationship this unconscious part can emerge essentially through certain modes of communication (tone of voice, rhythm and prosody of the voice, and structure and tempo of speech), which could be called the ‘musical dimension’ of the transference, and through dream representations. Besides work on the transference, the critical component of the therapeutic action of psychoanalysis is stated to consist in work on dreams as pictographic and symbolic representations of implicit pre‐symbolic and pre‐verbal experiences. A case history is presented in which dream interpretation allowed some of a patient's early unconscious, non‐repressed experiences to be emotionally reconstructed and made thinkable even though they were not actually remembered.
