Searching for (experimental?) horror music

I really liked nurse with wound - salt and Nurse With Wound - Soliloquy For Lilith. Their other stuff not as much, but of course I couldn't look into their whole discography. They seem to do lots of random stuff.

Sun O))) has also cool stuff, but Doom drone gets a bit repetitive after a while, unfortunately, for me at least :(

I wanna feel really uncomfortable, preferably without any vocals. I would like YouTube recommendations, but anything else is fine, too. Thank you so much!
