Act as a seasoned horror concept artist with 10 years of experience in creating eerie and unsettling environments. Design a chilling image of a haunted asylum, featuring [GHOSTLY PATIENTS] wandering the halls, their translucent forms glowing faintly in the dim light. The setting should include [FLICKERING LIGHTS] that cast eerie shadows on the peeling wallpaper and broken furniture. Add subtle details like [WHISPERING VOICES] echoing in the distance and old medical equipment scattered around, hinting at the asylum's dark past. The atmosphere should be thick with dread, making the viewer feel as if they're stepping into a place frozen in time, where the line between the living and the dead is blurred.
