Son needs his Sleeping Bag

I was dreaming that my son called me, and he forgot his sleeping bag on a backpacking trip. He was asking if we could bring him because there was snow on the ground, and he would need a really warm sleeping bag to stay out overnight. In the dream, I could see him hiking through the snow, so I needed to somehow get a sleeping bag to him. I suddenly had a sleeping bag in my arms, and I found myself hiking through the snow looking for him and his friends so that I could pass the sleeping bag off to him. It suddenly dawned on me that I wasn't sure how I would find him in this enormous snowy forest. I started looking around, and I could see a long snow coverered mountain range with trees and rocks, for as far as I could see. Suddenly, I saw my son and his friends walking toward me through the trees. I had somehow found them and could give him the bag so he wouldn't get too cold. Next, I was in a truck driving down the mountain listening to music on the radio, and I woke up in my bed.
