“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**king cat literally melting in it.” - Manchman67

“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 b*stard grabbed my neck. He had snuck up behind me and waited for just the right moment.” - rogerkjones

“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

“The Brave Little Toaster, that damn scene where the AC unit explodes after a raging cynical outburst of hopelessness and anger. Also the flower scene where it realizes it's alone and so it literally wilts and dies and the screen pulls away to black.

“Oh my God there's one scene that's f**ked me up. The Autopsy of Jane Doe. The two men are in the morgue and performing the autopsy but the radio keeps suddenly turning on to this old song that goes "open up your heart.." things start to get creepier and creepier and then suddenly they realize they're trapped in the morgue with this haunted body. The doors are locked in some way and suddenly they hear what sounds like a police officer or a guard of some sort. He keeps yelling from the outside "Open up! Open up!" The one mortician is trying but he can't and yells "I'm trying I'm trying!" All the sudden the man on the outside starts singing "open up your heart...."
