OMG...YES.. YES YES most definitely...that was a very bad way for Dean to End..... It should have been his dream maybe of foreboding with ......Like they were in a vampire camp and he could have been knocked out...somehow and is in a coma. And now he wakes up....in the Bunker, where it is protected from demons and Sam has been caring for him all this time. And they go back on the road, cuz Monsters are never dead...they come from past, lore, books, internet. Families come with generations of ghosts, monsters etc.... need more same and Dean....Maybe one get hooked up and has children and it starts with the mom again.....So whoever is on the the opposite and one with the child goes looking for the other and go back on the road on new adventures Sam and Dean went on when they were kids and visit those places, like the giant ball of string...hell I want to see that
