The Mindscape was the home of the Sleepwalkers.
It is set either (or both?):
It is uncertain if the Mindscape and the Nightmare realms overlap, of if some of the previously mentioned demons also served Nightmare, though Ian McNee's studies stated that Nightmare was set in the Archipelago of Anguish and Redemption. 
In the psychic Mindscape, Cobweb and demons such as the Agents of Despair, the Bad Ideas, the Cannibak, Depression, the Mindspawn (N'ogskak, Sk'obe, Sv'ara, T'opalli, and Esk'odin), Manic and Paranoia dwelt there, feeding off the thoughts and dreams of mortals, and were opposed by the Sleepwalkers.
History of location is unknown.
