Over the last 20 years the post-Bionians have begun nothing less than to spell out the beginning of the metabolizing process (reverie) in the analyst’s mind that takes place with under-represented mental states. This bold attempt leading to new discoveries, and its many possibilities for understanding patients, seems to have obscured differences amongst leading post-Bionians with regard to how they see the forms of reverie, and how they might best be worked with. With Bion’s perspective as a background, this paper explores three approaches, and how they differ with regard to whether one follows the views of early or late Bion. Technical issues associated with these views are raised. A clinical example is offered as one way to use reverie.
