Questions about vampires, do vampires really exist

Vampires have blood in their bodies, just less than humans, because the heart doesn't produce fresh blood.

There are a lot of them: mosquitoes, bats, cow hooligans, lice, etc.

Vampires are famous monsters in Western legends, why are they called monsters, because their position is very awkward, they are not gods, but they are not devils, and they are even less likely to be gods.

The original definition of a vampire is mainly derived from the legendary ** Dracula written by Irish writer Bram Stoke in 1897, and the image of vampires as pale, bloodthirsty, afraid of the sun, and immortal has been established in the public perception and has become an important role in the European and American literary galleries.

In the West, there are a large number of literary works and film and television works about vampires, and many people think that vampires are just people's fantasies and cannot be real, but in fact, "vampires" really exist.

A 22-year-old woman in India's ** Bangdamo district recently reported to the police, saying that her husband began drinking his own blood a few months after marriage. She has been drinking her blood for 3 years now. The woman said her husband used a syringe to draw blood from her arm each time and poured it into a cup to drink.

The woman's husband claimed that drinking blood made him stronger, and he did not stop even when his wife was pregnant. This is typical "vampire behavior", and many people think that the man is a vampire, but in fact "vampire" is a very rare disease - people with severe porphyria have a strange appearance.

Porphyria, also known as purple protein disease, is a disease caused by the deficiency of enzymes in the heme biosynthesis pathway, which is divided into two categories: hereditary and acquired, and patients will experience photosensitive dermatitis, abdominal pain, and neuropsychiatric disorders. Porphyria patients will be very sensitive to sunlight, because once the porphyrins gathered on the ** are exposed to the sun, they will produce a toxin, which will violently kill human tissues, so the patient will be afraid of the sun, gum damage will cause the teeth to be extraordinarily long, and there is a "vampire" image with pale fangs in the movie.

Most people with porphyria must have blood transfusions and heme supplementation. Some scholars mistakenly believe that in the early days when blood transfusion technology was still immature, people with porphyria may have swallowed other people's blood to relieve their own pain. As a result, the erroneous news that porphyria patients sucked human blood gradually spread, and through artistic processing, it evolved into the image of the final vampire.

So the vampire in the movie is real, but it's a rare disease.
