This week we talk to philosopher and animal ethicist David Peña-Guzmán about his new book When Animals Dream: The Hidden World of Animal Consciousness. David explores the idea that there really is a subjective world—a dream world—that lights up when animals sleep, what that actually looks like, and its moral implications.
