I'd just like to clear something up as its been bugging me slightly over the past few days.

Is Tidus really transported 1000 years in the future? Or does Sin just pluck him from 'dream' Zanarkand and into the real world?

We all know the real Zanarkand was destroyed all those years ago but 'dream' Zanarkand must have co-existed for some time because im quite sure Sin cant time-travel. Anyone care to expand on this?
