I wonder if Amara really resurrected Dean's mother. Here is what I think: Amara sent Dean back in time (Therefore he has no mobile- signal on his phone), removed Azazel from existence (therefore cleaned the timeline from all that mess, except it doesn't affect Amara & God themselves) and Sam was never harmed infected with demon blood, so Sam was no longer in the bunker when the Men of Letter assasin tried to kill him. You can clearly hear the bullet falling to the ground. Something similar was concluded in the TV.com review here: http://www.tv.com/shows/supernatural/community/post/supernatural-season-11-finale-episode-23-alpha-and-omega-review-146418071895/
