The entrance to the tunnel was his only way out. His mind kept turning while his eyes stayed fixed on nothing, because he could only see nothing. The absence of light left all but a blank black canvas for his imagination to create, destroy, scare and enlighten.
Post-dead battery, he wandered for an immeasurable amount of time, touching what felt like the same cold, smooth rock face over and over again. Right-hand fingers traced the rock wall on his right, gliding and skipping over minuscule peaks and ravines. Hovering alone in empty space was his left hand, indefinitely reaching for any sign of life.
