Abstract :
This research article aims to establish a new psychological perspective on Sidney Sheldon’s Tell Me Your Dreams by examining the novel through the implications of cognitive and psychological constituents that form its conceptual foundation. The study investigates how the narrative portrays the intricate dimensions of Multiple Personality Disorder (MPD), now clinically recognized as Dissociative Identity Disorder (DID), and its profound impact on the individual psyche. Sheldon’s work serves as an intriguing exploration of the human mind, depicting how trauma, repression, and identity fragmentation shape one’s consciousness and actions. The primary objective of the study is to analyze the ways in which MPD influences the behaviors, relationships, and self-perception of the novel’s central characters, thereby revealing the complexity of human psychology as represented in fiction. Furthermore, the research examines how MPD, despite its clinical recognition, has often been marginalized and misunderstood within broader discussions of mental health. The study draws upon Dr. Morton Prince’s seminal theory of Multiple Personality Disorder, which posits the coexistence of two or more distinct identities within a single individual, where a dominant or “core” personality interacts with one or more alternate identities. This theoretical framework provides a foundation for understanding Sheldon’s narrative treatment of dissociative conditions and their psychological implications. Using textual analysis, the research emphasizes the author’s literary mastery in portraying psychological realism, emotional conflict, and the dualities of selfhood. Ultimately, this study underscores how Tell Me Your Dreams functions not only as a work of fiction but also as a compelling psychological case study that bridges clinical understanding and artistic imagination, offering deeper insight into the human condition.
