This chapter explores disruption, one of the first aspects of trauma, as it is depicted in modern horror films. Trauma, characterized by events that overwhelm the individual's psychic processing capabilities, results in a profound shattering of basic assumptions about the self, others, and the world. In horror narratives, these disruptions are metaphorically represented through supernatural phenomena, monstrous entities, and apocalyptic scenarios, reflecting the incomprehensibility and unpredictability of traumatic experiences. Key themes in horror cinema include the fragmentation of the self and body (where characters encounter dark, unrecognizable versions of themselves), and the erosion of trust in interpersonal relationships (often depicted through metaphors of body replacement, possession, or the negative transformation of protective figures). Seminal stories like The Strange Case of Dr. Jekyll and Mr. Hyde and modern depictions such as Black Swan illustrate the concept of the double, which challenges the notion of a cohesive self. Similarly, maternal horror, as seen in Carrie and The Babadook explores the transformation of nurturing figures into sources of terror. The chapter also examines how trauma disrupts the individual's ability to predict and process experiences, leading to a persistent state of hyper-vigilance and emotional dysregulation. This is mirrored in horror films through the portrayal of haunted spaces and relics that symbolize the immutability of past traumas.
