What is self-deception according to Freud's theory of the psyche?

According to Osho, what Freud calls self-deception arises from the psyche’s split: a verbal, rational mind and a non-verbal, illogical mind that do not communicate. The conscious believes one thing while the unconscious moves you otherwise. But Freud misses the essential third factor—the witnessing awareness—which alone can see both halves simultaneously. Without this watcher, you remain divided and deceived; with it, division dissolves and authenticity becomes possible.
