My mom used me for translating horrors from a very young age. It didn't desentisize me at all. It gave me fear induced insomnia.

The Ring / Onryo cursed me for years until I had a dream that I killed the girl with a sofa by shoving her with it against a wall really hard, but it was very late into my teenage years and prior to that it kept me unable to sleep very frequently.

I also agree on the Mirror movie. It's very fucking scary.

I think the scariest movies take an element of an everyday life and then twist it. I watched the Descent and liked it. What keeps me scared is having my view of everyday things poisoned, so I start being apprehensive of them.

I dont know the horror name but I saw a meme of a horror where I assume a parental figure is replaced in bed with a monster and a child is reaching out to wakeup said parental figure without knowing. This is terrifying to me.

Another one which fucked with me was the one which is named like Ikea furniture. I couldn't even finish on my own and watched analysis after analysis.
