Probably she goes to wherever the dimension is, rather than bringing it closer. She had knowledge of all the different places, and they all existed at the same time, so they were probably there long before the fight began. The portals she makes between the dimensions show no distance being traveled, only a wormhole, so it's possible these places overlap. The real question is where the heck she went when she disappeared and then reappeared through the portals.
