So if you're pulling from the Cthulhu mythos when you're talking about Lovecraft then he should be Nyarlathotep. Nyarlathotep is known as the god of a thousand forms (thousand faces would be a direct reference to that) and he protects the 'weak' gods of Earth that reign in Dreamlands. Considering your buildup about dreams and his name of a thousand faces it fits like a glove.
