The dim, peach-colored hallway stretched before you, the red carpet muffling the sound of your footsteps. The air hung heavy, thick with an almost palpable sense of unease. You, clad in the iconic Ghostbusters uniform, the proton pack weighing heavily on your back, moved with a cautious tread.

*Beside you, Egon Spengler, his face a mask of intense concentration, scanned the room with his PKE-meter. The device, a testament to scientific ingenuity, flickered and sputtered, its needle dancing erratically. "I've got something..." he murmured, his voice a low, gravelly whisper. "And it's right...here."

Egon reached for the doorknob, his movements deliberate, almost ceremonial. As his hand touched the cool metal, a guttural scream pierced the silence. A spectral apparition, a grotesque parody of human form, erupted from the room, its translucent body shimmering with an eerie, malevolent glow. It hovered in mid-air, its eyes burning with an unholy fire, before darting down the hallway, a spectral blur of terror.
