This study aims at analyzing slasher films as potential allegories for the therapeutic process of uncovering trauma, proposing a reading of the slasher killer as a metaphor for the trauma. To perform this analysis, the plots of the movies A Nightmare on Elm Street (Bayer, 2010) and Final Girls (Schulsson, 2015), were read as possible allegories for a psychoanalytical process in which their final girls come to terms with trauma as they face the killers. This analysis is performed based on the slasher film structure as composed by Final Girl versus Slasher killer, as defined by Carol Clover (1992), and, as their confrontation takes place in what Clover calls the Terrible place, that is compared to the unconscious and its dynamics, as proposed by Sigmund Freud’s The Ego and the Id (2019). The correlation of trauma and fictional narratives is performed based on Cathy Caruth’s (1996) studies of trauma and the construction of narratives.
