Very often, a movie can be defined by one unforgettable scene.
These include the heartbreaking image of the girl in the red coat in Schindler's List, or Meg Ryan faking an orgasm in When Harry Met Sally, leading to the iconic line "I'll have what she's having".
And then there are the scenes that scared us silly!
Many people might actually not have seen these scenes, as they were burying their heads in their popcorn, or under the sofa cushions out of fear.
While those who were brave enough to watch them might still sleep with the lights on, if they can get any sleep at all.
Redditor MindlessMemory2294 was curious to learn which scenes still send shivers down people's spines even when thinking of them, leading them to ask:
"What is the most terrifying movie scene that still haunts you to this day?"
Stay out of the basement.

An image no one needs to see
"A movie called ‘Threads’ about nuclear war in Britain, where there’s a scene when the nukes first hit Sheffield."
"Genuinely one of the scariest scenes I’ve ever seen."
"You can see a f*cking cat literally melting in it."- Manchman67
Why I'm terrified of clowns
"The very beginning of the original IT."

"And then the little girl on her trike is gone."- Fit_Tumbleweed_5904

"The end of Carrie (1976) where Sue is laying the flowers on Carrie's grave and the hand grabs her wrist."
"A friend of mine was an usher at the theater and at just that moment the rat bastard grabbed my neck."
"He had snuck up behind me and waited for just the right moment."-
It's not healthy to hold a "Grudge".
"The Grudge (2004)-Most scenes but the one that always scares me is the scene where an office woman is heading home and the vengeful spirit of Kayako begins following her."
"The woman manages to escape her office and get home but is shaken by her encounter with Kayako and hides in her bed."
"The sheets begin to rise up and down and when the woman peaks under, Kayako greets her with that scary death rattle noise she makes and pulls the woman under the covers where the woman disappears."- Soggy_Willingness_65
I'll never go on the highway again.
"The log truck scene from Final Destination."- smokyporkbelly
