In a long and narrow corridor with stained and cracked gray concrete walls

In a long and narrow corridor with stained and cracked gray concrete walls, flickering fluorescent lights cast unsettling shadows. The floor is made of worn and dirty tiles. On the ceiling, at the end of the corridor, a dimly glowing red exit sign is covered with slowly dripping blood stains. Near the exit sign, blood smears on the nearby walls suggest a recent violent event. The weak and irregular lighting creates deep and distorted shadows, highlighting the exit sign with its blood marks, resulting in a dramatically impactful and disturbing image.
