Trauma, both in psychoanalysis and medicine, is often defined as an intrusion that exceeds the subject’s capacity for processing. The traumatic event would then become an internal foreign body, experienced by the subject but destined to remain external, freezing its narrative construction. From this perspective, the narrative of the traumatic event could be defined by the impossibility of fictionalization that characterizes psychical reality. However, psychoanalysis also allows us to consider the traumatic event as a potentiality. Within the framework of analysis and through transference, it becomes an opportunity for a subjective fiction. This fiction is a two-voice construction, and holds the potential to revive petrified psychical creativity. This movement also enables psychoanalysis to continue its theoretical evolution. Recent inquiry into the effects of French colonial history on individual subjectivities illustrates this: trauma is not merely that which lacks words or a narrative, but also that which lacks images, representations. Engagement with decoloniality reaffirms the analytic framework’s capacity to facilitate the co-construction of a narrative that permits a process of subjectivation.
