When he said 'even if I die, it will still be reality', he was specifically referring to the meteor that he imagined into existence. That doesn't mean everything he imagines will stay reality.

After he died, his "body" disappeared, along with the stage he created. So obviously the things he imagines into existence do disappear after he dies.

Also, he calls that dimension 'Galaxy Room', so the impression you get from that is it's basically a miniature galaxy, stars and all.
