It takes one to know one; or, whose unconscious is it anyway?

This essay explores the sometimes uncanny quality of unconscious experience and unconscious communication that often characterizes life in psychoanalytic relationships. As Ferenczi noted some 70 years ago, the psychoanalytic relationship may "significantly promote the development of subtler manifestations of receptivity." Special qualities of unconscious receptivity and deep points of contact in the psychoanalytic relationship are explored, with reference to the history of psychoanalytic ideas (e.g., Freud, Ferenczi, Singer, Loewald, Symington) and to findings from other fields such as contemporary quantum science. Clinical vignettes are provided to illustrate such phenomena.
