Using the psychotherapy of a fifteen-year-old boy, the author offers a theoretical and clinical reflection on the hallucinatory function and its outcomes. When the Ego no longer experiences the hallucinatory image as false, this image acquires an actualizing potential that blurs the boundaries of perception. When hallucination ceases to be a seed for creation and becomes instead a persecutory projection, what powers must the transference deal with?
