My aim in this paper is to examine the role of reverie in facilitating the rehabilitation and continuing development of the child-patient on his journey towards subjectivity. I begin by briefly reviewing the concept of reverie, as described by Bion and Ogden, and proceed with an examination of elements I believe are fundamental and common to both reverie and child psychotherapy, i.e. the presence of primary thought processes and primitive impulses. I then attempt to describe and demonstrate the atmosphere created by these elements, which pervades and threatens the inter-subjective dyad, using three examples from the psychotherapy of eight-year-old Jonathan. Next, I discuss reverie in the context of child psychotherapy, focusing on its relation to processes of destruction and recognition, discussed by Winnicott and Benjamin. I argue that reverie counters processes of destruction by recognizing the child-patient's hidden and fragmented subject-parts and his process of becoming a child-subject, that is, a child in continuous motion towards subjectivity. Finally, I reflect on the capacity for reverie, associating to personal experiences.
