Night attack

Last night I had a dream that I was driving a car with Adam wedged behind me, pinching my back relentlessly in one place. I thought he would tire of it, but he didn't. I told him to stop, but he kept on. I swiped at him with my hand, but he persisted. It was a steady pinch-pinch-pinch in the same spot. Finally I woke up, but the pinch-pinch-pinch continued. I made a swipe and my hand hit another hand. That's when I realized that the pain was real, but it was May, not Adam. She woke up and asked what was wrong. I said you're pinching me. I reached back and found the spot. I asked her to look where my finger was and tell me what she saw. She said, "Oh yeah, it's all red." I thought, well at least there's still skin there. Before I went back to sleep, I realized it was pretty dark. I held my hand up and all I saw was a silhouette. How did she see a red place on my back? I can still feel it this morning.
