"Ponies"

A dream. I was caring for a child. Sometimes it was a girl sometimes a boy. This an aura of when I looked after my nieces, and nephews.

My little one sang, and as she did she dreamed ponies to life. 

They were there, but not. Small like collies they pranced about.
When they slept they vanished. With song, and dreams more would come. A happy misty dream.
