This work explores some aspects of the roots and development of our psychic functioning: an unstable Gestalt, generating a need for certainty, and each subject's multiple identity.

The author has as a reference, the Freud's work ‘The Uncanny“. Freud describes ‘Unheimlich’ as an obscure feeling, a type of fright that leads back to something that has been known a long time ago and which reappears, arousing horror and allure, like something that cannot really be distanced from. Something unknown and on the other hand, too well known: an unpleasant perception, which is pushed away but immediately bounces back and must be recognized: it is not me/it is me. Simultaneous negation and affirmation, distance and uncanny closeness, at once.

This “it is me/it is not me” reflects the lability of the ego's boundaries, between the ego and the world, between the oneself and self-otherness and a coexistence of opposites inside oneself through multiple configurations, first of all the Double.
