My mysterious pebble

I was in the zoo and there were lots of people, they were in a rush.

I tripped over someone's leg and next to my head there was a pebble.

It was time to go home.

It was night time.

Everything was quiet.

There was an owl in my garden I couldn't sleep so I decided to dream about where my pebble had come from.

So I put my pebble under my pilow and I started dreaming.
