Have to also look at the differences between Anakin, Luke, and Rey. Anakin and Luke had good reflexes, which helped them as pilots and to survive on Tatooine. Anakin was about ten when he started training as a Jedi. Luke was 19. Far as I know neither had had premonitions or visions prior to being shown the "larger world" they were about to join. Rey, on the other hand, had the same untrained skill set that had helped her survive on Jakku... but there's also something else weird going on with her. She'd had premonitory dreams of Ahch-to and the island where she ultimately meets Luke for some time. The saber calling to her was something similar. It wasn't across time and space. It wasn't even when they landed on Takodana. It wasn't even when she entered Maz's castle. Just like Luke with the cave on Dagobah, it was only when she got close enough, in the right state of mind, that Something Happened. Luke felt cold. Rey heard someone crying. Both were drawn to whatever it was. I see both as the will of the Force, acting through whatever nexus was nearby. Neither Luke nor Rey were seeking the visions they got. Both were seriously rattled.
Yes, Luke had been being trained by Yoda for a bit by that point, and Rey hadn't, but the Prequels and Clone Wars have established that sometimes the Force does things without people initiating whatever. And we also still don't know where she comes from, who her parents are, etc.
