*Spoiler alert* I'm a tiny bit confused.......

Although I think this is one of the best films ever, evidently thoroughly intelligent and well directed, there's a bit I didn't quite get.
The main character keeps on reciting the story of the guy with the similar problem to himself, and the guy ends up unwittingly killing his own wife.
However, is Teddy telling the truth when he tells the main character that in fact this story is not about some other person and his wife, but in fact about the main character himself?
Thus, no crazy guy raped and killed his wife, but it was in fact him. If so, did he just create the memory of his wife getting killed in the bathroom? Have I missed something important?
(ps. I bloody love his tattoos)
