I enjoyed your description of LD . I think the geography and architecture created by the mind when dreaming is one of the most fascinating aspects of this . As I gain greater dream control I am looking forward to exploring lost cities and going into the strange towers and dream castles I see . This reminds me of what 19th C. Romantic poets and writers describe in their opium visions , Coleridge and De Quincey seem to have visited extraordinary cities of the mind which resemble visions we have in LD's .
