Is the PC an experimental Courser?

[Foky]

I made up this theory, out of thin air, that the player is actually Kellogg (Machinist Movie style). The idea came to me when I recently started my new playthrough and activated the cigarettes in the kitchen, where the PC wondered who put them there, and later the dog feed bowl where he wondered if they will ever find the dog. Now I have this theory that the PC's wife cheated on him and he murdered his family in blind rage and after he realized what he has done he became batshit insane and imagined that he lived before the the Great War.
