The essay offers a rereading of psychic regression as a generative movement rather than an involution, uncovering within it a possibility for subjective transformation. Drawing on Ferenczi’s notion of “Thalassa,” the return to the elemental, the fluid, the primordial ocean is interpreted not as an escape from reality but as a reactivation of a non-symbolized, sensitive dimension of the body. The desire for immersion in the aquatic expresses a need for disidentification from adult forms of subjectivity—a regressive gesture that becomes an opening to new modes of experience. The unconscious is conceived not as a closed structure, but as a topical and sonorous environment, echoing Fedida’s insight: a space where the subject is exposed to the other and to the silence of origin. Regression, far from being pathological, reveals itself as a condition for metamorphosis.
