"Create a terrifying Halloween-themed cemetery scene, filled with eerie, spine-chilling details. The setting should feature fog rolling across the ground, tombstones crooked and weathered with age, some cracked and covered in cobwebs. Include ghostly trees with bare branches reaching out like claws, and decrepit iron gates that creak ominously. Scattered around the graveyard are gnarled, twisted roots, broken crypts, and freshly dug graves. Add flickering lanterns casting an eerie glow on skeletal figures rising from the ground, with ravens perched atop the tombstones. The atmosphere should feel cold, dark, and haunting, filled with an unsettling silence broken by distant howls and whispers of the undead."
