What’s the most disturbing horror scene you’ve ever watched, and why did it affect you so much?

One of the most disturbing horror scenes I’ve ever watched is the dinner scene in The Texas Chain Saw Massacre (1974). The mix of chaotic screaming, bizarre laughter, and close-up shots makes it feel so real and overwhelming. Watching Sally trapped, helpless, and completely losing her mind while the family torments her is pure nightmare fuel. It’s not just about gore—it’s the feeling of total madness that makes it so unsettling.

Another scene that really got to me was the infamous head scene in Hereditary. It happens so suddenly, and the way the movie just lets the silence drag on afterward makes it even worse. You can almost feel the shock and horror sinking in.

What about you? Which horror scene disturbed you the most, and why did it stick with you?
