Horror Aficionados discussion

I'm rewatching some movies I loved growing up and I got interested about books of this subgenre. So, horror books/short stories that take place entirely or mostly underground, or the more important or horrific bits involve a subterranean setting or origin.
I'm more curious about the human-made underground, so things that take place in the subway system (like 2004's Creep, or Clive Barker's The Midnight Meat Train), the sewers (Stephen King's IT, 1997's Mimic), catacombs (2014's As Above, So Below), basements, large crawl spaces, secret or messed up underground levels or complex (Liminal Land analog horror), etc. But things like natural-made (cavern horror like 2005's The Descent) and weird horror (like Laird Barron's The Broadsword, or the tunnels in Stranger Things S2) are obviously also part of the subgenre.

I only have a natural cave one, The Luminous Dead.

Michael McBride (can't seem to get it to insert a link to his page here, but you can get there from one of the books below) has a number of books that would fit the bill here, though most are of the "natural" variety. There's Subterrestrial and Spores just to name a couple, but check out his catalogue. His books are freakishly well researched and very entertaining.

Also, not sure if this is exactly what you're looking for but Ararat involves the discovery of an ancient object in a remote cave, and I quite enjoyed it also. That's definitely my kind of horror!

The Catacombs by Jeremy Bates
The Descent by Jeff Long

Hide and Seek by MLV Sage. The idea of wandering around in a tunnel, and you are not alone, and while you read it you feel yourself getting scared is a nice feeling. I did read this with the light on.

This is such an interesting perspective on cosmic horror. The intersection of personal trauma and cosmic dread creates the most resonant stories. When the vast uncaring universe mirrors our own inner darkness—that's the sweet spot.

Dark Fantasy rather than Horror, but Dance of the Goblins has some very Horror adjacent things happening in the goblin caverns.
