Rey may have those abilities for a reason.
All three of Anakin, Luke, and Rey are basically "perfect" characters in their first episodes, it's not until the second chapter that they get some "dirt" on them.
Luke: Training Time: Approximately 5 minutes. Blows Up Death Star and out maneuvers "Chosen One" master pilot Darth Vader to do so. Saves galaxy (?).
Anakin: Training time - 0 minutes. 9-years-old, races pods (no other human can do this) at 1000 mph, blows up Trade Federation command ship saving the entire planet of Naboo.
Rey: Training time - 0 minutes. Uses several Jedi maneuvers (Jedi mind trick) with no apparent training, those her past is murky. Beats Kylo Ren, who isn't a "master". Technically it's actually Han Solo and Poe Damoreon who save the galaxy in this movie, Rey basically does nothing but overcome an injured Kylo Ren.
We'll see where Rey's character arc goes.
Luke has like 5 minutes of training too in ANH, lol, it's probable Rey has more actual Jedi training than he does, it's just repressed inside of her or laying latent or whatever. It looks like from that flashback that she's 7 or 8? She could have been training as a Jedi for a couple of years perhaps.
Or there is that reincarnation theory ... which to me wouldn't be so far flung since Star Wars very obviously borrows heavily from Buddhism and Eastern philosophy.
