Dream of caught, building, woke up

I was inside a small concrete building with 2 beds on either side. I was in one, and two people I couldn't see were in the other. We both were covered with a blanket. There was nothing else in the room there was opening for a window and door but there was no window or door. Outside I could nothing but blackened objects and the red glow in the distant background making me feel or think that the world was ending. We could feel an unbearable heat coming and we covered ourselves trying to not be consumed or killed by it. At one point a large blanket appeared and I tried to cover myself with it but it quickly caught fire and I threw it off me. Just then then, this heat was upon us, I could feel it. As it overwhelmed me, I found myself near the top of a maintain covered in green grass. The sky was blue with few clouds. There were others there. They all had this happiness about them, adults around my age. We were just there, sitting, smiling, talking to each other. Something like a lion was running and jumping around us. It didn't look real. It was light in color, nearly white, and looked as though it was put together with blocks of something that could have been wood. As ran towards me, I was just a little afraid and as it batted at my arm with its paw, I realized it was being friendly and wanted me play with him or her, I'm not sure. At that point, I woke up.
