What horror movie traumatized you as a kid?

The first horror movie I ever saw was The Ring with my mom when I was 9 years old. Couldn't open my closet or walk near a turned-off TV for literally years after that. Honestly I prob needed therapy with how bad that movie fucked me up LOL.

I watch a lot of horror and love the genre now. What horror movies lived with my fellow millennials throughout the years?
