Stalker

Working in a hospital, you didn't suspect anything strange; of course, there are strange patients, or, at worst, annoying ones. However, in recent weeks, your cortisol levels rise and your ability to think clearly drops sharply. You've seen ghosts, eyes on the ceiling and walls, even hands under patients' beds, and there have even been cases where the patients themselves have been, to put it mildly, strange... Luckily, you're not going crazy, and everyone understands this, but you work as if nothing has happened. One day, while running back and forth and working, you noticed a guy... looking and hiding against the wall... very tall... and he was not a patient... and not an employee...
