For me it was Event Horizon, that was scary as hell when I was a kid, I had nightmares for months.
The ring.
The Grudge. The Japanese original and the US ones.
To be fair, Event Horizon scared me as an adult.
In the vein of “kids are stupid”, the Never-Ending Story scene with the sphinxes.
You are welcome, my good man
Oh, man, Event Horizon was such a movie. “Where we’re going, we won’t need eyes” haunted me for a long time. And I had no idea it was gonna be a horror movie when I watched it.
Anyway, besides that one, the original Nightmare on Elm Street did me good. It was one of the first horror movies I ever watched, as my dad wanted to share it once he deemed me old enough. There’s something so terrifying about having to stay awake to not be murdered, but being powerless to do so. The most terrifying scene to me was the couple, where the woman got dragged across the ceiling and then the guy got arrested for her murder.
two movies came to me pretty vividly,
Spirited Away (2001), no-face is pretty scary even now, but the scene that disturbs me is at the beginning when Chihiro came back and find her parents have turned into pigs…
MirrorMask (2005), fittingly I watched this when I was sick with high fever and for so long I thought this movie was a fever dream, it haunted me for days until my fever subsides. I don’t remember anything about the plot, just that the atmosphere and aesthetic are nauseating
