The old, mysterious clock tower stood tall, its secrets hidden within its ancient stones. As I climbed the creaky stairs, the air grew thick with an eerie silence. I reached the top, where a lone clock face stared back, its hands frozen in time. Suddenly, the hands began to move, ticking away with a haunting rhythm. I felt a chill as the clock struck midnight, and a figure emerged from the shadows. It was myself, or so it seemed, with eyes black as coal. The doppelganger whispered, "Time is mine to keep," and vanished into thin air. I stumbled backward, realizing I was now trapped in the clock tower, forever bound to the rhythm of the clock. The last thing I heard was the echo of my own voice, whispering, "Time is running out."
