Nightmare
It was just a bad dream. That’s what he told himself, but he kept running anyway. He knew he was just hallucinating, but he sped up. He felt a sharp pain in his ankle, and heard the sound of claw tearing flesh, and when he looked down he saw blood. But it couldn’t be real.
His pace slowed because of the pain. He could feel the giant monster’s breath against his back, and he urged himself forward, faster than ever.
A purple tongue whipped around him and then flipped him into the air. He hit the ground hard, and he heard (and felt) a rib crack. The next day, Will woke up to a pain in his chest (What? he thought). He threw the covers off of his feet and turned his leg around. It was still bleeding.
His dreams were becoming real.
