That was my take as well. It was fun to watch, and I think they did a decent job of "for those in teh know, its the world between worlds, for everyone else....its just a force vision".
I "think" they were focusing on her survivor's guilt and how she was basically a child soldier, then soldier for most of her life, and she wants to be more than that. But I didn't really any get "resolution" either. I guess beating "dark Anakin" was her overcoming her own demons? Yeah was pretty confused there overall.
I will say the scene where she's in the smoke and you see the clone troopers start to run past her was really well done, the transition there was chef's kiss.
