Dream of crash

My fiance and I were in an unknown location that felt like a neighborhood. He was up a hill with our 1yr old visiting with someone and I was with our 3 yr old daughter, we were all happy, I was looking up at my finace and son and suddenly I turn to see an airplane, billowing smoke tumbling through the sky. I immediately see it's coming down between us, and look back up to my fiance and son and my fiance is gone and our son is running towards me smilling calling Momma... and the plane is coming and I tell our daughter to stay put and begin to run towards my son, still searching for my fiance and looking back at my daughter and running and I grab up my son and look back at my daughter who is crying for me to come back and the last thing I see is her face as the crash engulfs my son and myself
