The “pregnant moment” in analysis is a moment when past, present, and future, with their complementary constellation of ideas and affects, come together. The impregnation begins at a moment of après-coup (Nachträglichkeit) in response to an apparently banal event or la petite mort—an event that is ordinary but, in a particular moment, arouses profound affect that leads to a major shift in the analytic process. Using a vignette from clinical practice, this paper describes the conditions under which a banal event, such as double booking, may function as the taste of the Proustian madeleine for the analysand that magically sets off a symphony of childhood affects, fantasies, and memories on an unending stream of the present and past.
