Drawing on a historical detour, a personal experience and a clinical vignette, the author associates the crossing of an in-between space with a subjectivizing experience. This occurs on the bridge supported by theories with distinct poles, one more objectifying and localizing, the other closer to drive movements. This bridge evokes the preconscious, spans heterogeneous territories and becomes a vehicle of latent theories, a weaving of traumatic traces and their drive elaboration, whose sensory, memory and language-based modalities evolve as the work of the analyst and the development of transference/countertransference progress.
