In a chilling case report, doctors in Turkey have described what they claim to be a real-life vampire with multiple personalities and an addiction to drinking blood.

The 23-year-old married man apparently started out slicing his own arms, chest and belly with razor blades, letting the blood drip into a cup so he could drink it. But when he experienced compulsions to drink blood “as urgent as breathing,” he started turning to other sources, the doctors said.

The man, whose name and hometown were not revealed in the report, was arrested several times after stabbing and biting others to collect and drink their blood. …

The doctors said they found traumatic events in the man’s life leading up to his two-year bloodsucking phase. His 4-month-old daughter became ill and died; he witnessed the murder of his uncle; and he saw another violent killing in which “one of his friends cut off the victim’s head and penis,” the researchers write in the journal article.
