1. Late one night, a delivery driver pulled up to CVS Pharmacy with an urgent shipment. As he approached the door, he noticed something strange: the security light above the entrance seemed to flicker on and off in time with his heartbeat. As he got closer, he saw a shadowy figure inside waving frantically. ‘Open up!’ it whispered. The delivery driver unlocked the door, only to realize it was just his own reflection in the glass—caused by the dimly lit hallway and his deep breaths. He laughed nervously, shook his head, and said aloud, 'Guess I’m more tired than I thought.’
