Chapter 1
Sam tossed and turned in his sleep, the actions of his dreams causing his face to screw up and twitch. Sweat trickled down his creased forehead and formed little pools in the corners of his eyes. The blanket was twisted around his waist, limiting his struggles.
He could feel the hot breath on his face. Smothering him, choking him. The odour of the steaming air repulsive; the musty smell of soil mingling with the stink of rotting meat and blood. The yellow teeth hovering millimetres from his face shined with saliva in the moonlight, the long dark tongue curling and writhing around the massive chasm, eager for the taste of his sweet flesh.
Sam heard growling erupt from the depths of the animal's throat, sending a shiver down his spine. Try as he might, he couldn't move. He struggled in vain with his arms, but they wouldn't come to his aid. As he knew it would, the enormous beast let out one long, final howl of triumph, and sank his jaws into Sam's neck…
Tearing his eyes open, Sam 'Sammy' Winchester gasped for air as his body recovered from the shock of his latest nightmare. The motel room was dark, bar the thin sliver of moonlight shining in through the blinds. He lay there for a few moments, blinking away the sweat, before putting his head up to check on his older brother in the bed next to him.
He froze as his eyes processed the scene before him. Even in the blackness he could see the large dark shadow of an animal leaning over his brother's sleeping body, mouth wide open in a silent snarl. For god's sake Dean, he thought desperately, wake up.
His hunter instincts kicked in and Sam noiselessly lay his head back down and slowly reached his long arm down the other side of his bed, silently grappling for the rifle he had hid there only five hours earlier.
Pulling it out, he accidentally knocked it against the wall. Thud. The massive animal was still standing silently on Dean's bed, breathing heavily. At the sound of Sam's gun connecting with the wall; it swung around, yellow eyes glinting in the dark. At first Sam considered going limp and feigning sleep, but it was too late. He brought the butt of the rifle up to his shoulder and squeezed the trigger, but not before the snarling creature could leap from Dean's bed to his, lunging at Sam's shoulder. Knocked back against the wall, he cried out in pain as the beast clenched down harder on his joint.
He struggled with his free arm to push the animal off, the rifle laying forgotten on the floor. His eyes squeezed shut; Sam didn't see the shadow rear up out the opposite bed and dive at his attacker.
