Once upon a time, in a field full of fluffy clouds, lived a little sheep named Sally.

Sally loved to explore and play, but at the end of the day, she always felt sleepy.

One night, as the moon shone bright, Sally couldn't fall asleep.

She closed her eyes tight and counted fluffy clouds, but her mind was too busy to settle down.

Suddenly, a wise old owl named Oliver flew down from a tree branch and asked, 'Why can't you sleep, little lamb?'

Sally replied, 'I have so many thoughts in my head, and they keep me wide awake.'
