A man, who was diagnosed with a crippling condition, never thought that he will recover from the zombie condition. The British patient, named Graham, said that he was convinced that he was dead.

He said that he spent days in graveyard as it was the closest he could get to death. He was detected with rare Cotard’s Syndrome, which is also known as Walking Corpse Syndrome because sufferers tend to believe that they have become zombies.

Graham woke up nine years ago with the syndrome and lost his sense of smell and taste. He stopped eating, smoking and speaking.
After months of therapy and help from University of Exeter boffins, he coped with the condition.

The condition is known to affect just a few hundred people across the globe. One morning nine years ago, Graham told New Scientist that he felt as he was dead despite still breathing.

The condition emerged after he made a suicide attempt by taking an electrical appliance into the bath, while he was suffering from serve depression.

He visited the doctors after eight months and told them that his brain had been fried and was now dead.

“When I was in hospital I kept on telling them that the tablets weren't going to do me any good cause my brain was dead”, Graham wrote in New Scientist.
