ghastly

This term evokes a visceral reaction of shock or repulsion. When describing a scene or event, it suggests a level of horror that is physically overwhelming or morbid, often associated with death or severe injury. In a more casual or aesthetic sense, it describes something so tasteless or jarring that it becomes offensive to the senses. It also captures a specific physical appearance of pallor, where a person looks drained of life due to extreme terror or sudden illness.
