Chapter 1 deals at length with reverie. Ogden writes, "The unconscious conversation that in sleep we experience as dreaming, in the analytic setting we experience as reverie. The analyst’s reveries are his waking dreams" (p. 5). Ogden wants the analyst to gain access to what he calls the "continuous unconscious conversation with himself that takes the form of dreaming in sleep and of reverie in waking life" (p. 5). The title of the book comes from Ogden’s concept of the frontier between the unconscious and the preconscious, which he calls "the frontier of dreaming" and which he feels forms the "metaphorical place of that distinctively human conversation with ourselves" (pp. 7–8). It follows that psychoanalysis is a form of human relatedness that is "specifically designed to create conditions in which the conversations with one’s self that take place at the unconscious-preconscious frontier might be rendered increasingly audible, to analyst and analysand" (p. 11). Referring to his concept of the "analytic third," however, he says that the dreams and reveries generated by the analyst and the patient not only draw on the unconscious of the analyst and the patient as individuals but also have to do with "a set of unconscious experiences jointly, but asymmetrically, constructed by the analytic pair" (p. 11). This is the "analytic third" that Ogden has repeatedly written about, which he defines as an unconscious intersubjective construction.
