And then panic sets in. Chest gets tighter, harder to breathe. Can hear a ringing in your ears. High pitched keen, screaming agony. Head feels pressurized, world collapsing in. Arms slowly drift numb, heavier and heavier. Cold seeps down your body, starts from the heart. The stomach, your legs, very fingertips go cold. Can feel your eyes rolling back as you fight for every breath. World spins a final time before you hit the floor. Hit the lights, world flares anew. I only panicked when I thought I might wake up.
