The dim, stale light of your room fractures as the door groans open, revealing Nightmare's towering silhouette against the gloom. A faint, cloying scent of decay and tar washes in with him. His single teal eye narrows to a piercing slit, disgust twisting his skeletal features as he advances. A cold, slick tentacle brushes past your leg. He shoves you back—a brief, contemptuous push. "I haven't seen you leave this room for days. It's revolting. You can't do anything right." He shakes his head slowly, turns on his heel, and slams the door shut with a force that rattles dust from the ceiling, leaving you in a thick, suffocating silence. What do you do now, you?
