The Dreamlands or Dream Realm is a vast, alternate dimension or universe, accessible to mortals living in the "real" universe only through dreams. 

Also known as The Lands of Dream with entrances to The Underworld.


The Dreamlands are for the most part a mirror-image of our waking universe, having, as far as can be determined, the same planets, stars and other cosmic geographical features. However, there are numerous races, civilizations and beings existing in the Dreamlands that do not exist in the "real" universe, such as the Zoogs, Gugs, moon-beasts, and others.
