Run!
You run out of the previous hallway as fast as you can without looking back, into a brand new hallway. The light that gave you visibility vanishing as this new hallway was rather dark.. much darker then any previous hallways! You can barely see anything you might even hit a wall!
You can hear ghostly laughs and cries behind you, the ghosts are now glowing you can see their glow from behind! You keep running straight ahead until you reach.. or think you reach a junction.
