Do you think Dream Zanarkand disappears between sins?

Since Dream Zanarkand is a physical place made real by the fayth dreaming somewhere far out in the ocean. And Sin’s primary objective is to keep people from finding it as programmed by Yu-Yevon.

Theocratically wouldn’t someone be able to just stumble upon it during a calm?

Say me and my crew get lost in a storm and we’re out at sea lost for a few days a month or two after Braska’s calm. Sin is way too small to do anything to anyone currently.

We see some lights in the distance at night “Ah sweet! We found Luca let’s go!” So we correct course there and well, sure enough we find some new machina heavy, crazy city full of lights and people living their lives like it’s perfectly normally. Of course we dock and ask just where the hell are we? And we’re told Zanarkand like it’s the most obvious thing in the world.

After the shock ends I can’t imagine it would be too hard to figure where you’re at in the ocean using Zanarkand’s tech and star maps and stuff. We plot a course back to Spira and Luca.

Sure most people would say we’re crazy after being lost out at sea. But now knowing the course back, there’s nothing stopping us from bringing others to Dream Zanarkand. Especially while sin is still healing.

Granted the church might imprison us? Do they know about dream Zanarkand? Or just the truth about sin and yu-Yevon?

The fayth seem to claim they’ve been dreaming for the thousand years, no? So I can’t imagine it would disappear. But at the same time with no sin to protect it/be out there, what’s to stop people from exploring the ocean and seeing if there’s any new land masses other than Spira?
