You step outside, but as you head for the park, a thick fog sets in. You walk to the place where the park usually is, but there is no park. You were here yesterday, so it couldn't have been removed, and where it is there are many ancient trees thicker than houses and extremely tall. You turn around and you realise that the houses have all vanished! Every building, every bench, every sidewalk has disappeared! You look back at the forest and as if you were dreaming, a floating cottage no bigger than a studio apartment starts to soar above you. It has nothing visible that is causing it to fly, and when you glance up higher, you see a ladder being lowered. You climb up onto the little porch, and the ladder goes back up. You look down and notice that the little house is rising higher at a dizzying rate, until all you can see is the treetops. Then the cottage lands on one of the trees gently and the door creaks open! "Come in..." A cheerful but relaxed voice says from inside. "My name is Foggy."
