My only theory is that the fayth throught so hard to make Jecht real that he was able to do so, then due to the hatred that Tidus had (as well as his logic in looking outside the problem) made him real also. Ah well, thinking to hard on this will give me a headache.
An emotion, while not tangible, is real. An emotion is imaginatory, but no less real than when we yell at someone for berating their misuse of the word "prerogative". Sin and DZ are both dreams of the Fayth; that is how they are connected. But as I said, why Sin would want to interact so closely to DZ is another story.

Jecht was already real by the time he entered Spira, probably the reason he was made real was BECAUSE he had entered Spira. Same reason for Tidus (but his appearance in X-2 is of different origin, so don't include that). Tidus and Jecht didn't even know an outside world existed, and since they had no desire to do so, the fayth could not possibly have granted them their wish to see the world, they would not need the effort of making them real. Plus, Yu Yevon rules over DZ with an eagle's eye, making sure the integrity of DZ was kept. Why he missed Jecht and Tidus is also a theory to speculate upon.
