Monica Ali‘s Brick Lane depicts the protagonist Nazneen‘s silent acceptance of what comes to her life and exposes her exasperated angst which insidiously wriggles its way out through her inner trauma in silence. The lack of expression intensifies the impact of the trauma which goes unwitnessed, unspoken and unclaimed. Only her grieving daughter is instrumental in healing the mother‘s incomprehensible trauma by combining her dissociated self and showing an escape to freedom. This paper aims at exploring the traits of a Bangladeshi poor female immigrant Nazneen‘s disassociated self, and of the struggle and dilemma leading to subsequent trauma she experiences. A qualitative analysis of the novel is performed to trace and explore the struggles of immigrant characters who are in the quest for and formation of their essential identity breaking through the essentialized role, specifically, imposed on women by the chauvinist Bengali society. The study reveals that the dislocated female immigrant‘s multifold trauma becomes incomprehensible, subsided under layers of social impositions created by nationality, ethnicity, religion, culture, gender, and economic status.
