The Art of Fear: How to Write Psychological Horror that Stays with Readers

Creating fear in the hearts of readers is a fine art. While blood and gore can shock, psychological horror lingers long after the story ends. This genre taps into the depths of the human mind, unsettling us through uncertainty, paranoia, and the terrifying unknown. In this post, we’ll explore how to craft psychological horror that stays with readers, with a special focus on using an unreliable narrator, inner turmoil, and the fear of the unknown.

What is Psychological Horror?

Psychological horror leans into the unseen, the unspoken, and the unexplained. Unlike slasher horror, which thrives on explicit violence, psychological horror leaves much to the reader’s imagination. The fear generated here is more subtle but also more profound. This genre delves into how characters—and readers—perceive reality, often blurring the lines between what is real and imagined.

The key to psychological horror lies in creating an atmosphere of dread and unease. You don’t have to rely on monsters jumping out from dark corners; the true monster may be the protagonist’s own mind.

One: The Unreliable Narrator: Mastering Mistrust

One of the most effective tools in psychological horror is the unreliable narrator. This character invites readers into their mind, but what happens when that mind cannot be trusted? Whether due to madness, manipulation, or deliberate deceit, an unreliable narrator makes readers question everything they read.

How to use an unreliable narrator:

• Obscure the truth:  Allow your narrator to contradict themselves or omit crucial details. Subtle inconsistencies will make readers uneasy, unsure if they can trust the story being told.
• Evoke empathy: An unreliable narrator is not always a villain. They may be a character spiraling into madness or grappling with trauma. When readers empathize with the narrator, the horror becomes more intimate.
• Reveal their instability slowly: Gradually reveal that the narrator is unreliable. Start with small cracks in their perception, then widen those cracks until reality itself feels unstable.

Consider how Shutter Island plays with the idea of an unreliable narrator, leading readers down a path of growing uncertainty and paranoia.

Two: Inner Turmoil: The Horror Within

Another hallmark of psychological horror is inner turmoil—the battle that rages within a character’s mind. This can be their past trauma, guilt, or fear of losing control. Unlike external threats, inner turmoil is a deeply personal experience, one that readers can connect with on a psychological level.

How to craft inner turmoil:

• Build internal conflict: Give your protagonist fears and anxieties that make them question their own thoughts and actions. This could be as simple as doubting their ability to protect a loved one or as complex as losing their sense of identity.
• Use language that reflects chaos: As the protagonist’s inner turmoil grows, let the language of the story mirror that chaos. Sentences can become shorter, more fragmented, or disjointed, reflecting the crumbling state of mind.
• Balance external and internal threats: Let the character's mental state be as dangerous as the outside world. Their own mind becomes an antagonist, creating a dual sense of tension.

Stephen King’s The Shining exemplifies this with Jack Torrance’s gradual descent into madness. His inner struggles are just as terrifying as the haunted hotel he’s trapped in.

Three: Fear of the Unknown: What We Can’t See is Scariest

The fear of the unknown taps into primal anxieties—what we don’t understand often terrifies us the most. By withholding information, you can heighten the tension and suspense in your story. Let readers imagine what lies in the shadows rather than revealing every detail.

How to create fear of the unknown:

• Limit explanations: Instead of giving readers clear answers, drop vague hints about the threat lurking in your story. The more unknown, the scarier it becomes.
• Make use of ambiguity: Unexplained events, mysterious figures, or incomprehensible forces create a world where logic and reason break down. This creates an oppressive sense of confusion and fear.
• Use the environment: Let the setting itself become a source of fear. A crumbling mansion, an abandoned hospital, or a desolate landscape can all contribute to an atmosphere of isolation and dread.

In Bird Box by Josh Malerman, the terror comes from an unseen entity. The fear of the unknown grips both the characters and the readers, who are left in the dark, quite literally.

Writing Fear that Lasts

Writing psychological horror is about more than just jump scares or grotesque imagery. It’s about crafting fear that lingers, twisting in the reader’s mind long after they’ve turned the last page. By using an unreliable narrator, exploring inner turmoil, and embracing the fear of the unknown, you can create horror that is deeply unsettling.

When done right, psychological horror makes readers question not only the story, but their own perceptions of reality. As a writer, your goal is to plant seeds of doubt and fear in their minds, letting that tension build until it’s impossible to shake off.
