I think the existence of ghosts at all implies at the least some sort of spiritual plane or dimension that they’re partially in, or at the “worst” straight up magic wherein ghosts cannot interact with the physical world, even with gravity.
Being able to see may be part of that magic or a function of the spiritual plane as well.
That would, I think, be able to explain the events of the comic.
If instead we assume ghosts were entirely explainable by science, that could change things. We’d also have to account for the photons interacting with her and letting her see.
