The psychological thriller is a thriller narrative that emphasizes the unstable or delusional psychological states of its characters. In terms of context and convention, it is a subgenre of the broader ranging thriller narrative structure, with similarities to Gothic and detective fiction in the sense of sometimes having a “dissolving sense of reality”. It is often told through the viewpoint of psychologically stressed characters, revealing their distorted mental perceptions and focusing on the complex and often tortured relationships between obsessive and pathological characters. Psychological thrillers often incorporate elements of mystery, drama, action, and paranoia. Not to be confused with the overlapping psychological horror genre, which involves more terror than psychosomatic themes. (Wikipedia)
