Design a terrifying Halloween scene set in a fog-covered, abandoned graveyard. The atmosphere should be dark and eerie, with dense, swirling mist that partially obscures crumbling tombstones and dead, twisted trees. At the center of the image, a skeletal figure with glowing red eyes emerges from an open grave, surrounded by ghostly apparitions. Bats circle overhead, and a blood-red full moon casts an ominous glow over the entire landscape. The scene should evoke fear and dread, with sharp contrasts between shadowy darkness and the eerie glow from the moon and the supernatural elements.
