i would say they are actually about BFA and your mind is just contorting her image to the only other one you've had feelings for, maybe so you are thinking about someone that's long gone, then someone you just broke up with. dreams/subconscience mind is a very complicated thing.... all we humans can even do about it either, is speculate.... you'd be suprised how much you do stuff just because a part of your mind you can't hear, is telling you to..
