Check out the stories behind these real-life haunted houses!
Allegheny Lunatic Asylum (Weston State Hospital) - Weston, West Virginia
This abandoned facility has been featured on a few ghost hunting TV shows. Mentally-ill patients here thought they were cursed by witches or possessed by the devil. With much medical neglect and poor living conditions, many suffered and died here.
