This is a question that some of you will find stupid,or it is explained in the game.

Okay,is Tidus really a dream?

I mean,did he actually exist in Zanarkand?I know that Dream Zanarkand was a recreation of the original Zanarkand,but was Tidus truly a figment of the fayth's imagination?

Like,is it possible that he might have actually lived in original Zanarkand?

So,my question is:
Did Tidus actually exist at one point in time,or was he the fayth's creation?
