Children are the product of the environment they grow up in. An individual who has a healthy childhood is more likely to develop into a well-adjusted and responsible adult. Children who grow up in trauma-inducing environments often withdraw into themselves, attempting to form a protective shield around themselves. They have trouble distinguishing between the tangible and the imaginative. Hyperreality is a postmodern concept coined by French sociologist Jean Baudrillard. Hyperreality refers to the condition where reality and representations of reality are indistinguishable. This article aims to study the long-enduring effects of the trauma the narrator faced during his childhood in the novel The Ocean at the End of the Lane by Neil Gaiman through the lens of hyperrealism. This study also probes into the harmful effects of growing up in a prison-like environment on a child’s psyche. Moreover, the paper also seeks to establish that the narrator’s narration in the novel is unreliable given that he has not yet extricated himself from the prison in his mind and has not yet come to terms with the severe trauma that he faced in his childhood and, hence, finds it difficult to distinguish the truth from his imagination, thus leading to a distortion of reality.
