ok so i know tidus was supposed to be a dream of the fayth and all and when sin died the fayth stopped dreaming so he disappeared. but i watched the ending to X-2 and he just comes back and everythings ok. does that mean the fayth randomly started dreaming again? its really frustrating how the X series isnt really answering that question. so the question is...what do you think happened? anyone know the real, final answer?
