Most terrifying deadly organization modifications?

I’m looking for some really spine-chilling mods that will make my gameplay absolutely terrifying. Currently I’m running a few modifications including LGU, Mirage, Mental Hospital interior setup, and Giant Specimens expansion. These have been pretty good so far but I want to push the horror factor even higher. What are some of the most frightening mods you’ve tried that really made your heart race? I’m especially interested in ones that add new scary creatures, creepy environments, or jump scares that caught you completely off guard. Any recommendations for mods that will give me nightmares would be awesome.

Facility Meltdown destroyed me. Those alarms blaring while things are hunting you in pitch black - I kept alt-tabbing out every few minutes.

SCP-173 mod had me paranoid for weeks. Can’t blink normally anymore.

That Backrooms mod messed me up bad. Those endless hallways are creepy enough, but hearing footsteps behind you? Pure nightmare fuel. The Weeping Angels mod’s another one - you’ll never want to look away from your screen again.

The Skinwalkers mod messed me up. It mimics your friends through voice chat and I fell for it every single time - so damn creepy.

Bracken’s Revenge destroyed me. The Bracken becomes insanely aggressive and you never know what it’ll do next. I couldn’t explore at all - kept checking behind me every two seconds. Threw on some sound mods that made everything creepier and had to literally pause the game to chill out.

Lethal Escape destroyed me. Those maze levels where you’re getting chased through narrow hallways had me sweating bullets.

The Mimics mod broke my brain. Haven’t trusted a single item on the ground since a fake apparatus grabbed me.
