Sam looked over at his sleeping brother. He envied the calm steady breathing. He knew that by morning Dean would be rested and still have new thoughts and ideas about the case. While Sam feared he would sleep fitfully, if at all.

The fatigue finally conquered him. Sam fell asleep.

Sam and Dean walk into the clearing and stop. The wall is within arm's length. Suddenly, the ground beneath them quakes and the wall begins to sway. Small pebbles and bits of dust rain down. Sam grabs his brother by the shirt front and, in the same motion, he starts to step away. Instantly, he feels Dean's hands push violently against his chest, wrenching Sam's hands free. The force of the push propels him away and down to the ground. He is now safely out of range and can only watch as Dean is pelted with rocks until he is covered in dust and crumbled stones, no longer visible.

Sam awoke with a start and sat up. His breathing was audible as he gulped for air. He was unable to speak and heard his brother stir. The sound reminding him that he had been dreaming.

He looked across at Dean and again envied the rhythmic breathing and relaxed posture. He wiped the sweat from his face as he threw off the sheets. As he got out of bed, he looked over his shoulder to reassure himself that his brother was not disturbed. He decided that a splash of cold water might help so, he quietly walked toward the bathroom,unconsciously, creating a path that kept Dean in his sight.

Dean heard Sam slip back into bed as concern and sleep switched places in his brain. But, concern for his brother was a constant in Dean's thoughts, and once satisfied that all was well, sleep was able to regain its place at the front of the line.

A few hours later, Dean rubbed the sleep from his eyes and looked at his brother. He had his back turned and appeared perfectly still. This, Dean knew, was restful sleep. He quietly got himself out of bed and grabbed his things as he headed for the shower.

Once dressed, Dean had a fleeting thought to wake Sam but, let it go as he recalled Sam's restless night. Checking his watch, he decided he would give him a little more time. Dean went out in search of a cup of coffee.
