Haley Smith, 17, spent three years convinced she was dead. Smith suffered from the rare delusional psychosis Cotard's Syndrome, aka Walking Corpse Syndrome, where a person truly believes they are deceased or that parts of their bodies no longer exist. And what helped her finally snap out of it? Disney movies.

"I’d fantasise about having picnics in graveyards and I’d spend a lot of time watching horror films because seeing the zombies made me feel relaxed, like I was with family," Smith told The Daily Mail . She eventually told friends and family about her condition, who advised her to seek counseling.In addition to her help from a therapist, Smith also credits classic animated Disney movies with accepting the fact that she was indeed alive. ‘Watching Disney films gave me a warm, fuzzy feeling. ' The Little Mermaid , Aladdin, Sleeping Beauty, Bambi – I watched them all," Smith recalled. "I asked my boyfriend Jeremy: “How can I be dead when Disney makes me feel this good?”(Yes, she had a boyfriend during her time as a dead person. Take that single living people.)"Being a corpse was the most bizarre experience, but I’m so glad I managed to get out alive," said Smith.
