Trying To Get To You

One minute I saw you racing
Through grassy field from afar
I tried to follow and call out
You trotted faster away
Why do you not answer me?
I continue to try and catch you
The grassy field shimmer vanished
Melted into houses and stores
Around corner you disappeared
Where did you go my furry friend?
Your creamy coat blended
As you zoomed away to a blur
I looked around helpless
Worried I would not find you again
My heart pattering madily
To startle myself awake
Twisted in my sheets
I looked over to where you slept
You were there sleeping peacefully
I sighed; knowing you were still there
But, dream haunted me
Worried that you will leave me
How was I to know it would come to pass?
