Lovecraft’s Dreamlands is an alternative dimension that is accessible, at will, by young dreamers. Once a person reaches adulthood accessing Dreamlands is more difficult and can be accessed through the use of certain narcotics.
Once a dreamer enters into the Dreamlands they must walk down the Seventy Steps of Light Slumber. Once at the bottom of the stairs they will face the judgment of Nasht and Kaman the gatekeepers of Dreamlands. If these gatekeepers find the dreamer worthy the dreamer is allowed to descend the Seven Hundred Steps of Deeper Slumber and emerges in to the Enchanted Wood.
