How Did Kylo/Rey "Force" Chat?

Rian Johnson, the director of Star Wars: The Last Jedi, explained the Force connection between Rey and Kylo Ren. One of the chief complaints against The Last Jedi was its depiction of new Force powers. In the film, Rey and Kylo both communicate through the Force, as if they were talking to each other face-to-face. That differed from past films in which Force users could sense each others’ feelings, but not have a full-fledged conversation.
