Abstract
Fantasy tends to metastasize. It coopts and hijacks every resource available to the individual: emotions, affect, cognitions, memories, psychosexuality, and even one’s identity. It is addictive and anxiolytic. It is safe. It buttresses the fantast’s grandiosity (self-idealization). Actually, each of these dimensions of personality and functioning is mediated via the fantasy, colored and distorted by it. Gradually, all direct contact with and inner experience of one’s psychological world is lost. A robotic zombie emerges from within the fantastic space, regulated by its narrative.
