Your palms are sweaty, it becomes harder to breathe. There's a heaviness on your chest and limbs, and you can't move. Your hands are like ice, but the fire seems to devour from the inside. What is it? It's your fear that consumes you. Holds your mouth tight, not letting you make a sound. Huge, all-consuming, blind... It is everywhere and it is nowhere. It is only in your head.
