Движение. Место второе

The idea of a hidden world lurking beneath our own adds a chilling layer to the story. I'm curious whether this came from folklore, personal fascination, or another source.

The story managed to keep me hooked while also making me empathize deeply with the characters' struggles. Was this contrast intentional or a happy accident?

The creeping dread felt so palpable through mood and subtle details. I wonder what techniques the author used to create that sense of unease so effectively.
