Dark atmospheric horror metalcore inspired by a haunted house and a curse that follows people beyond its walls. Use low-tuned guitars, heavy drums, dissonant strings, distant creaks, subtle rain, and eerie room ambience. Begin with a slow ominous pulse and whispered English vocals. Keep verses restrained and claustrophobic, then build into tense pre-choruses with harsh vocals and a haunting melodic chorus. Add slow half-time breakdowns with abrupt stops, sudden silence, and unsettling vocal layers. Make the mood mournful, cold, and relentlessly frightening rather than theatrical or playful. End with a crushing final breakdown and a quiet, unsettling outro. Polished studio mix, clear vocals, tight drums, original melody; do not imitate any specific artist or film score.
