Dream Ledger for Me not You

The dream starts out with me riding in a jeep talking to a few people. In retrospect, I should have become lucid because I don't think I knew these people. The driver was a man, and there were two girls and me. Anyways, I glance out the windshield from the backseat and see a comet. It looks utterly magnificent. It's probably 20-25 times larger than the sun in the sky, right near the horizon. I point it out and we're all watching it when it hits the ground. We brace for the shock-wave and when it hits our little jeep is hurled backwards about 50 feet but manages to remain upright. We're all okay, a couple scrapes and bruises and psychological trauma, but okay. We get out of the car and head to the nearest house. Then owner lets us in and we're all pacing around his house excited and euphoric because we survived a comet strike. I remember pieces of our conversation.
"Did you see the comet?" we asked the home-owner. He laughed and replied,
"Well duh it was bigger than the sun!". The conversation went on a bit. Then he asked me about the impact. "How big was the mushroom cloud?"
"It was all I could see." I said. We were laughing and singing and partying all night, getting really drunk and celebrating the fact that we survived.
