Films in the psychological horror/thriller genre

Psychological horror and thriller is a genre that leans more on the human mind than physical danger. This genre is supported by fear and emotional instability. Instead of the unseen or fights. It creates tension by representing how characters think, feel, and showcasing them losing control. The fear comes from within: paranoia, guilt, trauma, or the inability to differentiate between reality from imagination, keeping the audience questioning whether the character is hallucinating, dreaming, or actually seeing what they see on the screen. Psychological horror goes a step further by creating a sense of unease, These movies often show character's confronting deeply disturbing ideas. What truly makes this genre powerful is its realism.

Here are some of my favourite examples: 

Shutter Island (2010)

Director: Martin Scorsese

This movie is explores the fragile boundary between reality and delusion. The story follows U.S.

Marshal Teddy Daniels, who travels to a mental institution along with his "partner" Chuck Aule to investigate the disappearance of a patient. As Teddy starts investigating, the narrative blurs the line between truth and hallucination with the help of revealing teddy's hidden traumas and buried guilt. Through a combination of eerie atmosphere, plot twists, and exploration of human psychology, Shutter Island creates a unsettling experience that lingers long after the credits roll. This movie is rooted in the mind of every person who has watched it, making audiences experience the protagonist’s confusion and paranoia firsthand. Although, it's been nearly 16 years since Shutter Island's release. The audience seems to confuse themselves till this day - There seem to be two main theories about the movie: Teddy is Teddy (he is actually a martial that the doctors make insane to hide their unethical experiments), or Teddy is Andrew (he was insane the whole time and the doctors are trying to cure him, as it is in the book).

The Platform (2019) 

Director: Galder Gaztelu Urrutia

This Spanish film drops viewers into a vertical prison where survival depends not just on appetite, but on human behaviour itself. At first glance, its premise is simple: a descending platform of food feeds inmates level by level. But as it moves downward, what remains becomes a brutal reflection of greed, inequality, and desperation. What unfolds is less about monsters and more about the unsettling truth of what people become when resources are scarce and morality is tested. The movie actually describes our Society in a capitalistic manner. Which quite frankly to me is a little better than communism. (capitalism says that we might have to cut heads but Communism says that there is always a head to cut) But that’s a topic for a world wide debate which won’t matter at all because we are not the ones who make rules. “You sure not be a communist Mr. Goreng.” -Trimagasi

Parasite (2019)

Director: Bong Joon ho

This film is a groundbreaking psychological thriller that blends dark humour with sharp social commentary. The film follows two families from vastly different economic backgrounds, gradually intertwining their lives in ways that become increasingly tense and unpredictable. Through its layered storytelling and striking visuals, Parasite explores themes of class divide, moral complexity, and the hidden tensions within modern society, creating a narrative that is both deeply engaging and unsettling. The Audiences are kept on edge because any discovery could lead to ruin or violence. Not a single character in the film is purely good or evil: the Kims manipulate others to survive and the Parks remain oblivious yet involved in their privilege. The characters deceive, scheme, and exploit social hierarchies, creating mind games and emotional tension. The horror comes from what humans do to each other rather than external monsters.

Us (2019)

Director: Jordan Peele

Us is a psychological horror film that blends suspense with deeper social themes. The story follows a family whose vacation takes a terrifying turn when they are confronted by mysterious doppelgangers: violent versions of themselves or “monsters” who are human like, forcing the audience to confront the dark potential within ourselves rather than supernatural horror. The film constantly builds anxiety and suspense with scenes where the family faces unknown threats in confined spaces. As the narrative unfolds, Us explores identity, fear, and the duality of human nature, using psychological tension to create a disturbing and thought provoking experience.

Forgotten (2017)

Director: Jang Hang jun

Forgotten is a compelling South Korean mystery thriller. The story follows Jin seok, a young man whose older brother is mysteriously kidnapped, only to return days later with no memory of what happened and unsettling changes in behaviour. As Jin seok slowly starts finding out the truth, the film unfolds into a mind twisting exploration of memory, identity, and reality. Making the audience question and confuse between delusion and reality.
