This thesis investigates imagination from a psychoanalytic perspective, integrating concepts from psychoanalysis and philosophy. In the psychoanalytic field, imagination is compared to Freudian constructions and Ferenczian reconstructions, in dialogue with the notions of autoplasticity and alloplasticity (Ferenczi), the areas of the mind (Balint), and potential space (Winnicott). The study examines how trances, regressions, and playing enable the recovery of a lost place of authorship following trauma. From philosophy, it draws on Kantian notions of reproductive and productive imagination, as well as the concepts of virtuality and multiplicity (Souriau, Deleuze, Guattari, Lapoujade, Lévy). Imagination is described as a shared handling of virtualities, operating between actualization and virtualization. Finally, literature is considered a privileged field in this process, as its dissolution of certainties and boundaries is essential for subjective reconstruction.
