DM: Tim Emrick
The following list contains material that I have found useful in running my Dreamlands D&D games. Not all of the RPG works listed here were written for D&D, but all provided useful background material and ideas.
Lovecraft, H.P. The Doom That Came to Sarnath and Other Stories. Ballantine, 1971. Dream-tales in this volume include the title story, "The Other Gods", "The Cats of Ulthar", and "The Quest of Iranon".
--. The Dream-Quest of Unknown Kadath. Ballantine, 1970. Contains HPL's only novella-length dream-tale (the title story), plus shorter tales such as "Celephais" and "The White Ship".
Myers, Gary. The House of the Worm. Arkham House, 1975. A collection of stories set in Lovecraft's dream-world.
Smith, Clark Ashton. Hyperborea. Ballantine, 1971. A collection of tales; "The Seven Geases" features the serpent people.
Davis, Graeme. "Dead Man's Quest", in Dungeon #107 (February 2004).
--. Tales of Freeport. Green Ronin, 2003.
"The Freeport Trilogy": Death in Freeport (Chris Pramas); Terror In Freeport (Robert J. Toth); Madness in Freeport (William Simoni). Green Ronin, 2000-2001. The classic trilgy of pirates and unspeakable cults. Watch the Green Ronin website for my 3.5 revisions of these adventures (available 2004).
Green Ronin Publishing. Several free online resources, including "Focus on Freeport" and a forum devoted to the setting.
Kirby, Brian E., et al. Black Sails Over Freeport. Green Ronin, 2003.
Pramas, Chris, and Matt Forbeck. Freeport: The City of Adventure. Green Ronin, 2002. The main sourcebook for all things Freeport.

Balsley, Erica. DnDChick's Call of Cthulhu d20 Page. Conversions of CoC monsters that weren't included in the d20 book, as well as a few original creations. Includes a Dreamlands page. [UPDATE: This site no longer exists.]
Cook, Monte, and John Tynes. Call of Cthulhu d20 Roleplaying Game. Wizards of the Coast, 2002. A d20 conversion of CoC, so compatible with D&D Third Edition (and includes an appendix about porting between the two games). Not much Dreamlands-specific material, but many standard creature, tomes, spells, etc., can be used as is.
