This song, and many others of Adam's can be interpreted so many different ways. That's why I love them.
When I hear this song, I can think of multiple meanings.
1:
He's not actually in a different "World". He's just saying that he's different than everyone else, and sees everything differently. If he could choose to see things like everyone else would, he wouldn't.
2: It could be that he feels like he's an another world when he's with the person that he's talking about in the song. He's saying that reality was nice, but now that he's seen this he would never want to go back.
