Scariest horror movies?

What are the scariest horror movies that you watched?

the serpent and the rainbow
misery
candyman (the original one)

Hereditary.
Suspiria.(either one honestly)
Annihilation.

Midsommar, Hereditary, 28 Days Later and sequel 28 Weeks Later, It and the sequel.

Well perhaps this movie isn't scary to most, but Paranormal Activity was pretty bad for me. I had a couple childhood experiences shortly after my mother passed away that were pretty abnormal. Since that point, I have never been one to watch paranormal-focused horror movies. But my wife talked me into shortly after the movie came out and man, that was such a bad idea. I slept like crap for nearly 2 weeks.

I can watch slasher flicks, gory horror, and pretty much anything else that isn't paranormal-related all day long, but there is just something about those paranormal movies (especially paranormal activity) that just rubs me the wrong way.

The RIng, it was the last horror movie I watched too

Hostel and A serbian film.

I absolutely adore horror and respect the fact that I might be desentisized to being actually scared by them, as I tend to watch one every night and have done so every night. Regardless, it's my favourite genre by a good mile.

I'm still hoping for that feeling when a movie hits you in the nerve and catches you off guard, maybe even creeps into your thoughts later when you're in bed.

So I turn to you my fellow horror fans, what are the movies you have found to be the scariest?

I personally have been most moved and terrified by The Grudge 2004 remake back when I was a teen, Shutter (thai), Halloween, Blair Witch Project, The Descent, It Follows and Hereditary, so kinda everything works for me, except maybe overtly excessive gore. Gimme your best shot!

The Ring, Midsommar and hereditary, these three movies scared the shit out of me

I love horror films and try to watch a few each week. I enjoy all sub-genres, such as torture porn, slashers, psychological horror, found-footage.... The list goes on. There are a few films I can't bring myself to watch a second time, simply because I'm so scared. These are:

Sinister
Goodnight Mommy
Hereditary
V/H/S 1&2 (most parts are boring but some f****dme up)
