Answer:
I dance on one feet and knows only one shape. Someone with same name as me is very good with directions
I am a shimmering field that reaches far. Yet I have no tracks and am crossed without paths.
You use me between your head and your toes the more I work the thinner I grow.
I have cities with no people forests with no trees and oceans with no water.
I am the only thing that place today before yesterday. (one word)
Runs over fields and woods all day. Under the bed at night sits not alone, With long tongue hanging out, Resting at your feet until we go for a walk
