The vision wasn't Natsu and Cana crying nearby Zeref. Those three are different fragments of Carla's vision. Her vision of Cana crying came true when Cana was at Mavis's grave. While the hand that seems to be dead belongs to Lucy who fell asleep due to Cana's Magic. Can't remember the other two but I'm pretty sure the Zeref one came true too. And the Natsu one may be him after fighting Gildarts.
