It's just a bad dream - a very bad dream.... Beware the night, for sleep provides another path to the Demiplane of Dread. In the unique domain called the Nightmare Lands, darkness offers not blissful slumber, but ultimate terror. Heroes enter this realm at the bidding of the night, drawn from their dreaming bodies and captured by an enigmatic figure known only as the Nightmare Man.
