Slow first-person camera movement steadily forward through the hallway. Preserve the architecture and lighting. The black tendrils remain almost completely motionless as the camera approaches. Only isolated loose tips move: one slowly retracts from the floor just before the camera reaches it, another gently curls around the edge of a doorway. The tangled pile on the floor subtly contracts inward as the camera passes beside it. Near the end, a single thin tendril hanging overhead slowly bends downward behind the camera's path, as though it has noticed the person passing beneath it. Extremely restrained movement. Nothing attacks. Nothing suddenly appears. No creature. No gore. Photorealistic psychological horror, quiet creeping dread.
