(This is takes place about season 12 after Jack was born.) Sam, Jack, Lucifer, were sucked into a portal and landed in a forest. Sam and Dean were both surprised when they saw their parents John and Mary Winchester their grandfather Samuel then Bobby, Micheal, Gabriel, Kevin, alive. Then there was Chuck and Amira (God and Darkness) Death, Crowley, and Rowena. All of them were confused as where were they all?
They walked around all together not trusting Lucifer. They all reached a city that was chaos, there were people running some sort of monster like things that none of them have seen before attacking people while other creatures were helping people. Buildings were burning and everything was chaos....they had just been taken out of one hell hole of a world and into another one.
