meaning of dreams pet

 I have recently turned 40. I dreamt last night that my childhood pet (a dog named lady) whom i loved and adored with all my heart was running around in a field with long grass, she had a pillow in her mouth and kept tossing it in the air and catching it while she was running in the field (it was a small red pillow I had when i was a teenager) After a while i couldnt see the pillow or lady anymore so i ran into the field calling out her name... I came to an area in the field where the grass was short (just one patch in the whole field where the grass was short) my red pillow was laying there but lady was gone. The sky was blue and sunny but the grass in the field was like a "hay" colour
