<p>This study examines the dual role of atmosphere as both a carrier of trauma and a medium for healing in Tan Twan Eng’s <i>The Garden of Evening Mists</i>. Through a close textual analysis of the novel’s protagonist, Teoh Yun Ling, and the symbolic garden she inhabits, works in, and later alters, the paper explores how atmospheric elements—such as natural landscapes, sensory triggers, and spatial dynamics—simultaneously evoke traumatic memories and facilitate psychological reconciliation. Yun Ling’s journey suggests that trauma, though inescapable, may be partially reconfigured through deliberate engagement with the environment. The garden, initially a site of repressed memories and colonial violence, becomes a space where fragmented identity and historical pain are confronted and, at moments, provisionally reshaped. By analysing interactions between Yun Ling’s physical labour (gardening), sensory experiences (scents, sounds, and textures), and the garden’s decay and adaptation, the study demonstrates how atmosphere operates as a dynamic interface between memory and agency. The novel’s refusal to offer complete resolution underscores the notion that healing lies not in erasing trauma but in redefining its role within lived experience. The garden gestures toward what might be called a postcolonial coexistence, yet this remains partial, provisional, and always vulnerable to disruption.</p>
