Suddenly, the screen went dark once more. A single line of text appeared in stark white: "I'm watching you, Emma."

Emma, a diligent software engineering student, sat in the campus library, the soft hum of cooling fans and hushed whispers creating a familiar backdrop to her late-night coding session. Her laptop screen cast a cool blue glow on her concentrated face as she meticulously debugged a complex algorithm.

The pulsing sound reached a crescendo, then abruptly stopped. Emma sat frozen, her heart hammering against her ribs. The library, once a place of comfort and intellectual pursuit, now felt like a cage. She looked around, her eyes darting between the shadows, half-expecting to see a face peering out from behind a bookshelf.

Trembling, she closed her laptop and shoved it into her bag. She needed to get out of there, to find someone, anyone, who could help her. As she hurried towards the exit, the memory of those distorted sound effects echoed in her ears, a chilling reminder that her digital world had been irrevocably breached.
