Guest Dream! From My Sister

This dream was not mine. It was dreamed by my sister, who told me about it the other day and I had to record it here. I was in it, and it seems to me that it has some meaning to it, so I asked her permission to post it here, and she wrote it out for me. This is in her words, the way she remembered it. =)

I woke up to the smell of smoke. I jumped up and ran to another room where my pregnant sister (Crystal), my baby nephew, and my other two nephews David and Levi were. When I got into the room David and Levi where holding on to Crystal and the baby. They just kept screaming "Mommy!" "Baby!" It was high pitched and made my heart sink.
I pulled David and Levi off of Crystal and the baby, and checked to see if Crystal and the baby were alive but there was no pulse. So I took David and Levi and ran outside. I put them on the side walk and told them to stay there. I ran back inside to the room where Crystal and the baby were. I checked to make sure they were dead. When I realized they weren't breathing and had no pulse I went and got my bearbear and my dog bear and ran outside.
There I meet the boys and a man. He opened up his van and I put the boys and my dog in the van and got in. I remember the man saying something but I don't know what. I remember watching the house go up in flames from the van. The last thing I remember was looking over and holding the boys and telling them everything was gonna be okay.
