One day, a boy named Tim saw a smooth rock outside. He picked it up and showed it to his mom. His mom said, "I guess that is a nice rock, Tim." Tim was very happy and played with the smooth rock all day.
At night, Tim put the smooth rock on his bed. He went to sleep and had a dream. In his dream, the rock was not a rock, but a comet! The comet was flying in the sky with Tim on it. They went up and up and saw the stars.
Then, something unexpected happened. The comet turned into a big, friendly bird! The bird took Tim back home and said, "Thank you for playing with me, Tim." Tim woke up and looked at the smooth rock. He smiled and knew that the rock was special.
