Prime Rib Nightmare (H-Bomb)

It's a little after 5am and I just awoke from a terrible nightmare. Lottie and I were at a construction site. There was a huge, wide and deep hole excavated with a tarp loosely over it. Some people were tossing a ball around, a soccer ball I think, and it fell onto the tarp just short of the edge of the hole. As soon as the tarp slipped from the edge, the ball and anything else on it would plunge in. Lottie ran towards the ball and stopped at the edge of the hole leaning out. I was shouting "No, No!" as I ran towards her. As I was nearly upon her I stretched out my arm to block her from stepping off, but I couldn't catch her. She stepped out - instantly falling down, down, down into the pit. I wasn't able to catch her. I awoke with a start with both hands clasped over my face. It was awful. I can't get the image out of my mind. My stomach feels like I have a rock in it or that it's empty, I can't tell which. Maybe writing it down will help me get past it. It's been a night of tossing & turning and terrible dreams about all sorts of people from my past. I wonder if it was that huge portion of prime rib that is to blame. Beef, it's what's keeping you up at night.
