In The Force Awakens, as Kylo Ren interrogates Rey, he tells her,
You've been so lonely. At night, desperate to sleep, you'd imagine an ocean. I can see it...I can see the island.
At the end of the film, Rey finds Luke Skywalker on a small rocky island in the middle of a large body of water.
The novelization says that the planet was
mostly ocean, dotted with a sprinkling of towering islands...
Is there any evidence that the island imagined by Rey is Luke's?
