Dream About Burnt Car Accident

I was walking around my neighborhood. Felt as if I were a teenager. I ended up in front of my house, in the driveway. I felt as my adult self once again. It was rather dark. Out of nowhere I see a car completely burnt to the frame. They told me there was an accident and my brother and son were inside. I knew there was not a possibility they could have survived that. I instantly felt empty. I dropped to my knees crying. I was thinking this is the worst thing that could ever happen to me. I was so disturbed that I woke up. I still felt uneasy a bit after waking up.
