'I can feel the same thing I felt whenever I was about to die...' Once that idea passed in his mind, he felt a long and excruciating chill that made all his body shiver.
Dean's instincts were screaming to him to back away immediately and create as much distance as he could from the figure that was hidden in the pitch dark of that part of the cave. However, his legs didn't move at all, he couldn't even bring himself to move his fingers.
'Do something! Do something now or else it will kill you!' He tried to awake from that state just with his willpower, but it seemed almost impossible.
Dean's body just began to move once he heard that the Dread gave a step forward. The boy finally released the air that he was holding and stumbled backward.
