There's a theory floating around that Rey is familiar to the Skywalkers even though the Skywalkers don't really know who she is, is because she is Anakin reincarnate. If mitichlorians grind your gears, this theory will too. Main point was Luke never had such a strong force reaction to his fathers lightsaber. Rey having so much clarity on past events in her flashback even though she was born what? 15 years later?

I did have a theory that Vader hired someone to create his own progeny. And Rey is just that. Just never got completed until much later.

I do have a strong feeling Luke knows her.Knew about her and organized her exile to Jaaku with Max Von Sydow.

And apparently Von Sydows character is in fact Kanan Jarrus from Rebels. Which if you're following S02, Kanan and crew are preventing the inquisitors from collecting force sensitives. So maybe Rey is just one of them without being a Skywalker in any form.

Rebels is now official canon so I can only assume they really want to tie something from the series into the films.
