Creepy analog horror voice generator, old vintage microphone, worn wooden casing, rusty metal mesh, eerie glowing red LED lights, mysterious fog surrounding, abandoned asylum, dimly lit dusty room, cobwebs hanging from ceiling, flickering fluorescent tubes, haunted atmosphere, disturbing whispers, unsettling creaks, ominous humming noise, worn leather-bound book lying nearby, cryptic symbols etched onto walls, ominous shadow looming in background, low-key eerie ambient lighting.
