Prompt: An eerie scene set in a dimly lit, decrepit room where a man, bathed in the glow of an old lamp, is feverishly typing on a weathered typewriter. The man is hunched over, his face obscured in the shadows, adding an element of mystery and fear. Beside him, his young son innocently plays with a tattered, deflated ball. The surroundings should feature subtle but sinister details, like peeling wallpaper or cracked windows, adding to the foreboding atmosphere.
