"A truly terrifying Halloween background set in a nightmarish landscape

"A truly terrifying Halloween background set in a nightmarish landscape, where the sky is shrouded in dark, swirling clouds that barely allow any moonlight to seep through. The foreground is dominated by a haunted, decaying forest, with twisted, gnarled trees whose bare branches resemble skeletal arms reaching out ominously. The ground is littered with dead leaves, broken branches, and the remnants of old, forgotten graves, some with shattered tombstones and exposed roots. In the center, a massive, demonic jack-o'-lantern with fiery, glowing eyes and a jagged, menacing grin casts an eerie light that illuminates the scene in a hellish orange-red glow. Surrounding the pumpkin are ghostly apparitions, their faces contorted in silent screams, and shadowy figures that lurk in the darkness, barely visible but undeniably present. Cobwebs hang from the trees, and giant spiders crawl along them, their eyes gleaming with malevolent intent. The entire scene is bathed in an oppressive, dark atmosphere, with a chilling wind that seems to whisper of the horrors that lie within."
