I might have something for u. "The static speaks my name" is short to play but realy fun game. Not too scary tho. Its more about uneasy vibe and abstraction, but i hope you would like it. Also its free on steam!
i think "No, I'm Not A Human" is a pretty good short horror game! in my opinion it has a really interesting concept and builds a good atmosphere. it's currently a demo which is why it's pretty short but still a good play
