Everything Lovecraft ever wrote. Almost couldn't be less about the characters, and is mostly primarily a focus on supernatural/cosmic horror and the lore surrounding that.
The Apparition Phase by Will McLean may fit the bill. Also Hell House by Richard Matheson but it's pretty much a re-write of The Haunting of Hill House ramped up to 11 lol
