This webinar deepens the work at the level of essence in interpersonal relationships, exploring how to recognize and navigate the deep dynamics that emerge between two or more people. Based on 2-person- psychology, the course focuses on the "middle ground" or liminal space, an intermediate area in which the meanings are negotiations and the relationships regulate themselves. The webinar examines how to identify and work with the signs that emerge between energy X (energy of the disorder) and the energy U (ordinary identity), two forces that shape the interactions. Partecipants will reflect on interactional microprocesses, discuss and work on interactional (circular) situations (in relationship), in which two minds/bodies connect in a sort of inter-corporeality, the synchronization of their dreaming bodies in a session.
