An excellent Land of the Mists accessory providing a wealth of mechanics and lore concerning dreaming. There are some innovative cosmological ideas concerning the dream plane geography (not restricted to Ravenloft) which deviate somewhat from canon. The setting itself is roughly split in two: the clinic for the mentally ill in Nova Vaasa, and the Nightmare Lands themselves, a colourful chaotic island which features a lot of extravaganza. The clinic does not deviate from the typical Victorian specimen, but the Lands have some twists, the most interesting of which is probably the "race" of Abber nomads with their unique worldview: believe only in what you see at any particular moment, don't trust in the falseness of the cause-effect chain and disregard both past and future.

All in all a very enjoyable reading, containing 4 mini-adventures. I assume that incorporating the material in the campaign may prove somewhat demanding of both players and DM, due to the need for tightwalk roleplaying, the danger of meta-thinking and the malleable terrain of dreams. ( )
