Im pretty sure the continuing blurry images of Rinoa that keep coming up are because Squall is begining to forget. In the Ragnarok Laguna said something about not forgeting your friends and that if you remember your friends they will exsist....or something along those lines. I think Squall (mainly because off believing he is alone in that desert place) starts to forget his friends (mainly Rinoa) and tries to rmemeber but cant quite get it.....and thats the reason for the blurry images of her.....thats how i see it. The only thing i dont get is the space helmet exploding and Rinoa dying.......perhaps he is so messed up that he thought he remembered that happening or something.
