"Help!" Ziana screamed, pounding on the doors as the train rumbled through the tunnel. Her heart pounded, and the darkness around her seemed to intensify. There was complete silence except for the sound of the train and the frantic beat of her heart.
"Don't waste your energy, dear." A low, musky voice echoed from the darkness behind her. She knew the voice too well. It belonged to the mind demon that had haunted her yesterday. She could feel its presence, even though it was nowhere to be seen.
She shut her eyes tightly and clutched onto the door, too scared to turn around and face the danger awaiting her. It was all inside her head. She could escape it if her thoughts became idle again.
"Idle minds are the devil's workshop, darling," the demon's voice echoed again, and she could hear his little laugh inside her head. "So, the harder you try, the more fun it will be."
