Was Tidus real or was the place he came from a dream? What happened at the end? Did he die? Or did the "dream" break when Sin died and thus he broke?

I'm so confused.

Tidus is a dream of the faythe.  During the war between Bevelle and Zanarkand, it became apparent that Bevelle was going to obliterate Zanarkand due to their superior machina.  Yu Yevon got all the survivors up to Mt Gagazet and bound them there so that they would dream and their dreams summoned up their memories of Zanarkand (why there are so many pyreflies there).  The dream world of Zanarkand is out on the ocean so Yu Yevon created Sin as armor and protected the dream world of Zanarkand.  But after many years, he kinda lost his humanity.  Once you stop the dreamers from summoning, everything that was summoned disappears (the dream world of Zanarkand, the aeons, and Tidus).  It's how Jecht and Tidus got swept away to Spira.  They were already on Spira -- just in this little protected plot of ocean where Yu Yevon was directing the summoning by the people of Zanarkand.

If you play FFX-2, you get a little more backstory on who Tidus was based off as Tidus was just an aggregation of the memories of the people who actually lived in Zanarkand.
