In this chapter, the author examines Sigmund Freud’s “Two principles” paper through the lens of the analytic couple”s capacity for symbol formation and mutual dreaming. He addresses Freud’s ideas about the nature of thinking and discusses “post-Kleinian and Bionian developments regarding some technical aspects that allow us to deal with patients who have deficiency in their thinking capacity.” Freud, of course, emphasised that thinking develops through the postponement of the pressure to discharge unpleasurable experience and that, therefore, thinking is “experimental action”. During the analytical session the patient unconsciously dreams what is happening and these thoughts are expressed through the verbalisation of conscious fantasies, feelings, and ideas that cross the patient’s mind. As the analytical process develops itself the dreams of both members of the analytical dyad constitute a complex, dreams-for-two, in which it is not always possible to differentiate the contribution of each one. The consciousness seeks to know the reality beyond the pleasure and displeasure sensations.
