A psychological thriller is a genre of fiction that focuses on the mental and emotional states of its characters, often exploring themes of fear, obsession, and manipulation. These stories typically involve complex characters who may struggle with their own minds, leading to suspenseful and unpredictable plots. The tension often arises from the characters' psychological conflicts rather than physical threats. In a psychological thriller, the narrative may include elements such as unreliable narrators, twisted relationships, and moral ambiguity. This genre often delves into the darker aspects of human nature, making the audience question what is real and what is imagined. Examples of psychological thrillers include works by authors like Gillian Flynn and Patricia Highsmith.
