(CNN) -- Huddled in the hallway of his Alabama home with three of his friends, Tillman Merritt had a gut feeling to jump into a closet as the massive twister barreled into the Tuscaloosa neighborhood. Moments later, he was the only one to survive. "I just heard a voice in my head saying 'go to the closet, go to the closet," Merritt said. The closet walls pushed down on him as a roar surrounded him, followed by the sounds of pieces of the house snapping off. Then the crack of glass was heard, and insulation was flying everywhere. When it was over, there was just a small hole for Merritt to crawl out of. Except for the closet he was in, the entire house -- and his three friends -- had been flung across the street.
