However he wasn't created in the same way we would conceive creation of another person I'd say he is very much real in that world.

Actually it is possible that he was still conceived by Jecht and Tidus's mother. They were corporeal after all as well so nothing forbids that. It is never hinted though if his own birth was actually through the summoned dream or if he was conceived the ordinary way, still making him bound to the dream.
