A refrain from a dance rock song soothes my ears as I regain consciousness. Headache pulses between my temples and all my joints are sore. My left knee hurts. I slide my hand down my leg and touch, through a rip in my jeans, the mushy softness of a wound. My breathing gets faster, as random flashes of myself cycling along an urban roadway blast in my mind like a display of fireworks. No room enough to stretch my limbs. The surface under my body has the roughness of wood.
