This can be assumed because the Hound is seen in the same area, and it matches a physical location to where Bina first saw the Botfly
Bina is transported to the Botfly's Moment by the Hound at the end of Chapter 1. This is where she first encounters the Botfly in the form of a TV. Ms. Hyung and Mr. Petrovich are here as well, apparently held captive. They were placed here by Gregor, albeit against their will.
At first, Bina observes that it feels like dawn, but that this doesn't make sense because there is no birdsong. She later notes that the air feels "stale."
