While the mother archetype traditionally symbolizes nurturing, care, and unconditional love, its negative aspect, the devouring mother, embodies traits of control, manipulation, and suffocation. Drawing on Jung's theories, and his concept of the collective unconscious and symbolic archetypes, particularly the mother archetype, through close textual analysis and theoretical insights, this paper explores the dual nature of the mother archetype and its psychological implications in Gillian Flynn's novel "Sharp Objects, 2006". The paper analyzes the character of Adora Crellin as an embodiment of the devouring mother archetype. Through Adora's behaviors of possessiveness and emotional abuse towards her daughters, Camille, Marian, and Amma. The paper illustrates the detrimental effects of a suffocating maternal influence on individual autonomy and psychological well-being shedding light on themes of dual maternal influence, traumas, and complex mother-daughter relationship. Through this psychological approach, the paper aims to contribute to the broader discourse on maternal psychology and its impact on human development.
