What settings should i set so minecraft looks like a horror game?

Texture packs, seeds, mods, settings… Anything, i just want it to look like something is haunting me so i get an urge to make a shelter/hideout and gather resources and stuff, because like this its almost as if i have no reason to play, but i want to:3

There's plenty of horror texture packs you could download. I recommend Slenderpack though, it's really creepy.

Low.

I would play with a photo realism texture pack (There are quite a few different ones that are for different versions of minecraft) and for the settings, turn brightness down to moody. If you have a really good computer, you can also try the shaders mod.
