No, I don't think so. I think it's Sora's island.

[Whatever that island is called, that world even. He's sure he hasn't been there.]

It's really nice. There's a beach there! And um, a cave I think and a bridge...it's always hot when I dream of it and they used to play with these wooden swords or race around I think!

[Roxas nods after a moment's thought.]

I want to go sometime. I want to see that beach! Did you know Lea and I went to the beach before? It was really really awesome!
