I'm not sure which I would love more that Alan Wake, Cauldron Lake, Dark Place/Presence, etc were just an AWE and part of a larger and wacky-er world that the FBC monitors and tries to understand or if the FBC, AWEs, The Board, etc and everything we learned of in Control were just creations of Alan's in order to help him escape the Dark Place and defeat the Dark Presence once and for all. 10 years is a lot of time to write up a pretty elaborate and intricate story...
Both would be really cool and have a lot of appeal.
