stay alive for any extended period without food, water or fresh air. An alternate explanation for noise is the bubbling of escaping gases from natural decomposition of bodies. Another likely cause of disordered tombs is grave robbing. Folkloric vampirism has been associated with clusters of deaths from unidentifiable or mysterious illnesses, usually within the same family or the same small community. The epidemic allusion is obvious in the classical cases of Peter Plogojowitz and Arnold Paole, and even more so in the case of Mercy Brown and in the vampire beliefs of New England generally, where a specific disease, tuberculosis, was associated with outbreaks of vampirism. As with the pneumonic form of bubonic plague, it was associated with breakdown of lung tissue which would cause blood to appear at the lips. In 1985 biochemist David Dolphin proposed a link between the rare blood disorder porphyria and vampire folklore. Noting that the condition is treated by intravenous haem, he suggested that the consumption of large amounts of blood may result in haem being transported somehow across the stomach wall and into the bloodstream. Thus vampires were merely sufferers of porphyria seeking to replace haem and alleviate their symptoms. The theory has been rebuffed medically as suggestions that porphyria sufferers crave the haem in human blood, or that the consumption of blood might ease the symptoms of porphyria, are based on a misunderstanding of the disease. Furthermore, Dolphin was noted to have confused fictional (bloodsucking) vampires with those of folklore, many of whom were not noted to drink blood. Similarly, a parallel is made between sensitivity to sunlight by sufferers,
yet this was associated with fictional and not folkloric vampires. In any case, Dolphin did not go on to publish his work more widely. Despite being dismissed by experts, the link gained media attention and entered popular modern folklore. Rabies has been linked with vampire folklore. Dr Juan Gómez-Alonso, a neurologist at Xeral Hospital in Vigo, Spain, examined this possibility in a report in Neurology. The susceptibility to garlic and light could be due to hypersensitivity, which is a symptom of rabies. The disease can also affect portions of the brain that could lead to disturbance of normal sleep patterns (thus becoming nocturnal) and hypersexuality. Legend once said a man was not rabid if he could look at his own reflection (an allusion to the legend that vampires have no reflection). Wolves and bats, which are often associated with vampires, can be carriers of rabies. The disease can also lead to a drive to bite others and to a bloody frothing at the mouth. In his 1931 treatise On the Nightmare, Welsh psychoanalyst Ernest Jones noted that vampires are symbolic of several unconscious drives and defence mechanisms. Love, guilt, and hate are emotions that fuel the idea of the return of the dead to the grave. Desiring a reunion with loved ones, mourners may project the idea that the recently dead must in return yearn the same. From this arises the belief that folkloric vampires and revenants visit relatives,
