The Dreamlands are apparently divided into four regions:
- The West contains the Steps of Deeper Slumber and Enchanted Wood by which many enter the Dreamlands. Other points of interest include the port of Dylath-Leen, the Dreamlands' largest city; the town of Ulthar "where no man may kill a cat," the coastal jungle city of Hlanith, and the desert trading capital Illarnek. Here, too, lies the land of Mnar whose gray stones are etched with signs and where rise the ruins of the great Sarnath.
- The South, home of the isle of Oriab and the areas known as the Fantastic Realms;
- The East, home of Celephaïs, a city dreamt into being by its monarch Kuranes, greatest of all recorded dreamers, and the dangerous Forbidden Lands;
- The North, location of the feared Plateau of Leng, home of man-eating spiders and the satyr-like "Men of Leng".
Other locales include the Underworld, a subterranean region underneath the Dreamlands inhabited by various monsters; the Moon, accessible via a ship and inhabited by toad-like "moon-beasts" allied with Nyarlathotep; and Kadath, a huge castle atop a mountain and the domain of the "Great Ones".
