David’s caller suggests that we are living in a simulation worthy of Nyarlothotep. Like David, I don’t buy the simulation idea, but the creeping crawling chaos notion seems spot on.
I’ve been an H. P. Lovecraft fan for decades (that’s the primary reason I linked to this). I will grant that Lovecraft’s plots can be repetitious, but I’ve read no other author as adept at creating atmosphere as he. The Dream Quest of Unknown Kadath is my favorite Lovecraft tale, followed by At the Mountains of Madness.
The Cats of Ulthar is just a bit too realistic for my taste.
