How can Rey use the Force when she just discovered it is real?

This is yet another biggie – Rey manages to use a Jedi Mind Trick on a Stormtrooper (portrayed by Daniel Craig, if you didn’t know), even if she believed that the Force is just a myth a couple of days ago. How did she do that?

This needs to be addressed in the Star Wars: The Force Awakens sequel. If it won’t, then it means that anyone aware of the Force can use it, with no training at all.

There is, however, a hint of an explanation in the movie itself, in the vision she has when touching the lightsaber. Apparently, those visions are in some way connected to her own past. And, if it is so, then she was in some way present when Kylo Ren and the other Knights of Ren killed the padawans from Luke’s Jedi Academy.

And if indeed she was present, we can assume that she also had some training in there. If so, why doesn’t she remember?

We may further assume that her memories were blocked and started to come back when Kylo Ren extracted the information he needed from her. But, again, this is just another supposition.

Rey is too big a character for her past to remain a mystery – we do hope that. So we may find an answer to this question in Star Wars: Episode VIII.
