Watching myself crash on a plane

I'm on a plane returning from a business trip with a coworker. The plane seems to be crashing but I'm not sure. The plane then tilts so I'm sitting at a 90 degree angle and I'm sure it's crashing. My coworker and I are suddenly in sleeping bags on a sidewalk as if we're camping out in a line for tickets, my coworker is asleep. I see the plane that we are also still on diving towards the ground in the distance. I quickly try to wrap our sleeping bags around us to protect us from impact. The plane crashes in the distance and I sit up and put my hand on my coworker's back to see if she's OK. I realize I'm dreaming.
