16 Horror Movies That Are So Disturbing You’ll Only Be Able To Watch Them Once

Some horror movies are fun to watch with friends — the kind that make you jump, laugh, and sleep just fine afterward. Then there are the others. The ones that crawl under your skin, live rent-free in your mind, and make you swear you’ll never watch them again.

1. Hereditary (2018)

It’s not the jump scares that get you in Hereditary — it’s the suffocating sense of doom. What begins as a story about a grieving family slowly morphs into something far more sinister, and you don’t even realize when the shift happens.

Director Ari Aster takes his time, letting grief rot into horror until it becomes unbearable. Toni Collette’s performance alone is so raw and emotional that it’s almost uncomfortable to watch. By the time the supernatural elements fully reveal themselves, you’re already emotionally drained.

There’s something deeply wrong about Hereditary — not just in what happens, but in how it makes you feel. It’s not a movie that scares you in the moment; it’s one that stays with you, whispering dark thoughts when the lights go out.

2. Midsommar (2019)

Who knew a movie drenched in sunlight could be this horrifying? Midsommar takes place almost entirely in broad daylight, yet it’s one of the most visually disturbing horror films of the decade.

Ari Aster strikes again with another story about grief — this time mixed with cults, codependency, and the slow unraveling of sanity. Watching Florence Pugh’s character lose herself in a foreign community that worships death as much as life is both mesmerizing and nauseating.

It’s not gore that gets to you here; it’s the emotional manipulation, the psychological suffocation, and the smiling faces that hide utter madness. When it’s over, you don’t just need a break — you need a hug and maybe a long vacation.

3. The Exorcist (1973)

Even decades later, The Exorcist hasn’t lost its power. This isn’t just a horror movie — it’s a spiritual experience that tests your faith, nerves, and stomach all at once.

For its time, the effects were groundbreaking (and still stomach-churning). But it’s the psychological weight of seeing innocence corrupted that truly terrifies. Linda Blair’s transformation into a demon-possessed child is so realistic that even seasoned horror fans struggle to rewatch it.

There’s something deeply human beneath all the horror — a mother’s desperation, a priest’s crisis of faith, and the haunting question of whether evil ever truly leaves. Watching The Exorcist once is an unforgettable experience; watching it twice might just be too much.

4. The Texas Chain Saw Massacre (1974)

Nothing about The Texas Chain Saw Massacre feels like fiction — and that’s exactly what makes it so disturbing. Its documentary-style grit and relentless chaos make you feel trapped inside the nightmare yourself.

Leatherface isn’t a polished movie monster; he’s raw, messy, and terrifyingly human. The film’s low-budget realism adds to its authenticity, and by the end, you’ll feel like you’ve survived something you were never supposed to see.

Even without excessive blood, the atmosphere is suffocating. Every scream, every sound of that buzzing chainsaw feels wrong in the best (and worst) way. It’s the kind of movie that makes you want to shower afterward — twice.

5. Martyrs (2008)

This French horror film isn’t just disturbing — it’s emotionally brutal. Martyrs explores pain, suffering, and the human obsession with transcendence, but it does so in ways that make most viewers look away.

What starts as a revenge story becomes a philosophical nightmare about martyrdom and meaning. It’s unflinchingly violent, but the violence isn’t there to shock — it’s there to make you question why you’re watching at all.

By the time it’s over, you’re not sure if you’ve witnessed horror or despair. Martyrs doesn’t let you off easy; it lingers, it festers, and it reminds you that some truths — and some images — are better left unseen.

6. The Human Centipede (2009)

Just hearing the title is enough to make people squirm. The Human Centipede became infamous for a reason — it’s pure body horror pushed to grotesque extremes.

The concept is as simple as it is horrifying: a mad surgeon “connects” people in ways you wish you could un-imagine. It’s not about fear of monsters or ghosts — it’s about the fear of what one human can do to another.

Even seasoned horror fans admit this one crosses a line. It’s less about jump scares and more about psychological disgust. Once you’ve seen it, you can’t unsee it — and you’ll probably never want to try.

7. Antichrist (2009)

Lars von Trier’s Antichrist isn’t your typical horror film. It’s art-house terror — slow, symbolic, and deeply disturbing in both imagery and emotion.

The story follows a grieving couple retreating into the woods to heal, only to descend into madness and violence. It’s visually stunning yet filled with some of the most graphic and shocking moments ever filmed.

This is the kind of horror that makes you uncomfortable not just because of what happens, but because of how it reflects human pain. Antichrist is less about scares and more about surrender — and once it’s over, you’ll wish you could forget it entirely.

8. Mother! (2017)

Darren Aronofsky’s Mother! feels like a panic attack come to life. What starts as a quiet domestic drama turns into a chaotic nightmare about fame, ego, and the destruction of innocence.

Jennifer Lawrence’s descent into confusion and terror mirrors the audience’s own. Every moment grows more surreal, violent, and symbolic until the film reaches a crescendo of pure insanity.

It’s not an easy watch — and that’s the point. Mother! is a biblical allegory dressed as a psychological horror film, and it doesn’t care if you “get it.” By the end, you might just feel like you’ve survived a fever dream.

9. The Babadook (2014)

Sometimes the scariest monsters are the ones we create ourselves. The Babadook takes that idea and runs with it, transforming grief and depression into a literal creature of darkness.

Essie Davis delivers a powerhouse performance as a mother unraveling under the weight of loss and motherhood. The film builds tension slowly, blurring the line between supernatural horror and psychological breakdown.

What makes The Babadook so disturbing isn’t just the monster — it’s what the monster represents. Once you understand the metaphor, it’s impossible not to feel it on a personal level. It’s haunting in all the quiet, human ways.

10. Eraserhead (1977)

David Lynch’s debut film feels like a nightmare you can’t wake up from. Eraserhead combines surreal imagery, industrial noise, and abstract horror into something completely unique — and deeply unsettling.

The film doesn’t rely on gore or jump scares. Instead, it traps you in a world that feels wrong in ways you can’t explain. The deformed baby, the claustrophobic sets, and the droning sound design all work together to erode your sanity.

It’s not an easy film to understand or even endure. But once you’ve seen it, you’ll never forget it. Eraserhead doesn’t just disturb you — it changes how you think about fear.

11. The Blair Witch Project (1999)

Before found footage became a trend, The Blair Witch Project made it terrifyingly real. The shaky camera, the screaming in the woods, and the unseen terror created an atmosphere of pure panic.

Its genius lies in what it doesn’t show. Your imagination does the heavy lifting, filling in every dark shadow with something worse. The lack of closure makes it feel unfinished — like the horror might still be happening somewhere out there.

Even after 25 years, the realism still gets under your skin. Watching it alone at night? Forget it. Once is more than enough.

12. Audition (1999)

Don’t be fooled by the first half of Audition — it pretends to be a romantic drama before it morphs into a full-blown nightmare.

Director Takashi Miike masterfully lulls the audience into a false sense of security before delivering one of the most shocking twists in horror history. The final act is so graphic, tense, and psychologically twisted that many viewers couldn’t finish it.

What makes Audition unforgettable is its precision. Every sound, every movement builds dread until the reveal hits like a gut punch. It’s not just scary — it’s deeply, emotionally disturbing.

13. Funny Games (1997 / 2007)

Michael Haneke’s Funny Games isn’t content to scare you — it wants to punish you for wanting to be scared.

The film follows a home invasion, but the real horror is its awareness of the audience. The killers talk to the camera, rewinding scenes and toying with expectations until you realize you’re the one being manipulated.

It’s not gory or flashy, but it’s emotionally exhausting. Funny Games forces you to confront why you watch violence in the first place — and by the end, you’ll wish you hadn’t pressed play.

14. The Nightingale (2018)

Revenge and horror collide in The Nightingale, a film so emotionally and physically brutal that many viewers couldn’t finish it.

Set in 19th-century Tasmania, it follows a woman seeking vengeance after a horrific act of violence. What unfolds is both a story of empowerment and an unflinching look at the cruelty of humanity.

The violence isn’t stylized or sensationalized — it’s raw, realistic, and horrifyingly personal. You don’t just watch this movie; you endure it. Once is enough.

15. Eden Lake (2008)

This British horror film feels terrifying because it could actually happen. A couple’s relaxing getaway turns into a survival nightmare when they cross paths with a group of violent teens.

There’s no supernatural threat here — just the sheer unpredictability of human cruelty. The tension builds slowly, turning from discomfort to panic in a way that feels horribly plausible.

By the end, Eden Lake leaves you shaken and angry, with an ending so bleak it feels like a punch to the gut. It’s one of those films that sticks with you — but you’ll never want to revisit it.

16. Salò, or the 120 Days of Sodom (1975)

Even among horror fans, Salò is notorious. Pier Paolo Pasolini’s adaptation of the Marquis de Sade’s work is often banned, censored, and whispered about rather than watched.

The film depicts unspeakable acts of degradation and control under the guise of political allegory. It’s intentionally repulsive — a protest against fascism and power disguised as horror.

There’s nothing entertaining about Salò; it’s an endurance test meant to confront the viewer’s tolerance for suffering. Watching it once is enough to last a lifetime — and maybe too much even then.
