Drowning in a crowded Pool

"I was in a pool, and people were all around me, close enough to touch. Somehow I had slipped under the surface. I kicked and pushed with everything I had, trying to lift my head above the water, but nothing worked. Each time I rose, I sank again. The water poured into my nose and I could feel it filling my lungs, heavy and cold. I fought harder, my arms flailing, but no one seemed to notice. The pool felt endless, and the surface stayed just out of reach. When I woke up, I had the worst headache and my body was burning hot. My chest was tight, and I gasped for air. It was the most vivid dream I had ever had, and for a while I could still feel the water in my lungs as if I had truly been struggling to breathe."
