Just a mirage...

As you get closer, you begin to feel more and more confident that the scene before you is real. You begin to run, gaining much faster on the sight before you, then as you come within what must be fifty feet of it, you fall, tripping on your own happy feet, your chest striking the ground hand, shaking you up some. When you look up again, expecting to see lush trees, you see only desert.

Quickly, frantically, you hop up to your knees, then your feet, turning repeatedly, looking around for the sight that you were so convinced was real. By the time you accept it as a mirage, you have no idea which direction you came from, and the sun is growing hotter above.You drop to your knees, wanting to cry. But you don't. No, there's no sense in that. It helps nothing. You stand up again, looking around.

Four directions: forward, backward, left and right.
