Billie crept through the dimly lit hallway of the abandoned hospital, her footsteps barely making a sound against the cracked tiles. Faint moonlight spilled through shattered windows, casting jagged shadows along the peeling walls. She held her breath, heart pounding in her chest.

Her blood turned to ice as heavy footsteps thudded closer, each step dragging like something massive pulling itself forward. Frozen in place, she knew she had only seconds to decide — run or hide.
