Frozen lake and the red Bench

"I was walking across this massive frozen lake behind my high school gym, even though I knew the ice was way too thin to be carrying my weight. The air was totally still, but every step I took made this deep, booming echo under my boots. I had to get to a red bench on the far shore to hand someone a pair of scissors, but the shore felt like it kept getting further away the faster I walked. All of a sudden, the surface under me shifted from clear ice to thin, jagged sheets floating on pitch-black water. A spiderweb pattern of cracks shot out from beneath my feet, and cold water started pooling around my ankles. I stopped dead in my tracks, terrified that if I even shifted my weight or breathed too hard, the whole section would collapse and pull me under. My chest felt so tight I couldn't draw a full breath, just watching the dark cracks spread wider and wider toward me until I snapped awake in the middle of the night."
