I think you answered your own question. Rey finally embraced/realized her own destiny in that moment. That, and it was Luke's lightsaber. I think the music worked perfectly fine without having to allude to her lineage. That, and at this point do we really want them to double back? If Johnson did one thing good with TLJ it was to say that bloodlines don't matter. I really like that message. And now we want them to go back on that and say, "Actually, screw that, Rey needs to be related to someone cool to make a difference in the galaxy." At this point, that would make no sense to me.
So after reading this I was about to say that I guess we are just supposed to completely right off Rey's vision scene and the fact that is so completely powerful in the force. Means nothing. Bloodlines don't matter.
And I started thinking, again, how lame that is. The vision at Maz's place seemed to absolutely be a huge piece of the puzzle in this trilogy. But you go me thinking here about re-interpreting the vision scene from TFA. So I broke down the vision scene again and I am thinking more now that JJ and RJ may have more on the same sheet of music than most of us have thought.
First, she is drawn to the saber. Why? Rey (as we come to find out soon) is very powerful in the Force. The saber was the weapon of one of the most powerful Jedi ever, Anakin. The saber was in the possession of a powerful Jedi who defeated him, Obi Wan. The saber was later given to the son of Anakin who also became a powerful Jedi, Luke. The saber could be said to have some sort of mystical force imprint on it of the Jedi that formerly had it.
Next scene is the hallway in Cloud City that leads to the platform where Vader lops off Luke's hand, holding the saber, and tells him he is Luke's father. You can clearly here the aggrieved Luke "noooooooooo". Why? Two thoughts. First, it underscores that Rey needs to find Luke, not just for the resistance but to help her understand the Force. Second, Rian hits on the concept of "balance" between the light and the dark. The saber was wielded by Anakin/Vader when he became a Sith (the dark) and by Luke (the light).
Next scene is a grieving Luke at the scene of the massacre, most likely assumed to be after Kylo and the KOR kill all of his students. Why? Again, it underscores Rey's need to seek out Luke for the reasons mentioned above.
Next scene Is Kylo and the Knights of Ren at the massacre. Why? To underscore the ruthless nature of the dark side, of Kylo, and that they massacred the next generation of Jedi students. In other words, this is your enemy Rey.
Next is little Rey on Jakku with Unkar Plutt crying watching a ship take off. Why? Maybe because of exactly what Kylo told her. Her parents were drunks that abandoned her. This one is hard to rationalize because why was grown Rey living alone in a rusted out AT-AT if she was sold or left to Plutt? But I think the point is, yes, your parents are scum that left you behind. You came from nothing.
Then to Starkiller Base. Obi Wan's voice is clear. Why? Probably just because Obi Wan had a strong connection with the saber and he seems to be calling out a warning to Rey through the Force. Then Kylo appears with saber ignited. This clearly drives home the point that it is her destiny to face him, to destroy him if need be. It is inevitable.
TL, DR: I think the title "The Force Awakens" really means just that. The Force awakened in Rey. A nobody, from nobody parents, who is being guided by the Force. The Force brought her to BB8, to Finn, to Han and Chewie, to the Saber, to Luke, the cave, and to face Kylo, not once but twice already. Not saying any of this changes my tune on TLJ. It doesn't, I think it sucks. But maybe there was more coordination between JJ and RJ than many of us thought. based on the vision sequence almost everyone determined that Rey was somehow a Skywalker or a Kenobi or even some spawn of Palpatine. But all along, she was just Rey.
