One Friday Mrs. King asked her class to write a story after class. “Use your imagination!” she cried, “You can write your story about anything.” Kenny looked worried. “A story?” he thought, “What could I possible have to write about? I don’t know any stories.” The bell rang and all the kids went home.

The next day, Kenny sat at his desk at home, thinking and thinking. The warm sun was shining through the windows, making him drowsy. And soon he fell fast asleep. As he slept, Kenny began to dream about fantastic things.
