[elric]

Given my name [1], lucid dreams are something that I used to interested in and have experimented a lot with. In the Elric of Melniboné books, most of the empire spend most of their lives in dreams, as a hedonistic escape from reality. Needless to say, the empire decays.

Who needs an empire when every citizen has a kingdom in their dream world? ;) Hadn't heard about those book though, will look into Moorcock.
