Writing Prompt: Dark Prison

Here is what I got: 

My head hurts. I can't see. I realize my eyes are closed. I open them; but I'm still shrouded in darkness. Fear sweeps across me. I try to sit up but fall back, my head dizzy and throbbing. I take a deep breath then cough. The air's thick, moist, and warm. It smells of grass and earth. I turn over. My face rests on a soft, fuzzy surface. The scent's even stronger. I can almost taste it. I grope with my hands. Just as I thought, damp, compacted dirt and patches of moss? God, I hope it's moss - not mold! I push up onto my hands and knees and groan. My voice comes back to my ears quick and solid. I feel around and soon find a wall. It's soft and spongy like a cork. I walk the circumference of the room, twenty paces. No door. My heart pounds in my chest. I close my eyes pressing my back against the wall, breathing, calming a panic attack. My ears pick up a sound. The wind howls just outside. A faint breeze touches my cheeks - brief relief from the dank air. Where there's a breeze, there's a way out!
