The concept of the unconscious is at the heart of psychoanalytic study and practice since its beginnings. A human being's awareness is bounded, and the deeper layers of the mind are mostly inaccessible. Sensations, emotions, dreams, symptoms or creative work may give us a glimpse of the landscape and mediate our relationship with the forgotten, the unknown and the unknowable. The mind has its ways to remain organized and balanced through the development of barriers or shields. However, overwhelming emotional experiences may break through and confront us with the unbounded, infinite and chaotic nature of the unconscious. Resorting to Matte-Blanco's bi-logical theory, this paper aims to explore the effects of trauma on the mind, both as a disruption of psychic barriers and as an unbearable emotional experience of infinity within.
