Make no mistake, the lens through which your protagonist sees everything is never neutral, but always encoded with inside info—beliefs—that help her interpret everything she sees, and therefore what she does as a result. And here’s the surprise: every one of those beliefs is subjective, not because she’s so caught up in her own world she can’t see the “real” world, but because there is no “real” world. At least, not in the way we’ve been taught there is.
