Aimlessly wandering the Dreamlands was much easier than aimlessly wandering Earth, especially if you were a powerful dreamer.
Well, easier wasn't exactly right. In this civilized era, Earth had significantly fewer things that were trying to kill you. But the Dreamlands had abolished many of the inconveniences of travel, like passports and being too out of shape to walk far and waiting in line to see the Eiffel Tower, which somehow was never quite as beautiful as you imagined. And being a dreamer simplified things: a strong dreamer could always get a berth on a ship, to handle such minor matters of weather and wind as they come up, and it wasn't at all hard to suggest that that fruit tree around the bend should be in season or that some dry wood should be over there or that those gathering stormclouds should go bother someone else.
But even the Dreamlands couldn't get rid of every inconvenience associated with wandering the earth.
Which is to say that his feet hurt.
