In Star Wars: The Last Jedi Supreme Leader Snoke says that
it was he himself who was connecting Rey and Kylo Ren via the force, minutes before Kylo Ren killed him.
But later on, on the planet Crait, Rey sees Kylo when she is about to board the Millenium Falcon. She closes the door in the apparition's face. How did this happen?
Wasn't Snoke, who was connecting them, dead?
