Vampires of the 1700's
	As we all know there were times in the early 1700's when people were aware of vampirism and blamed most sicknesses on it. They believed in those times that vampires were created from a suicide, a very violent death, or if  the person was a witch. It was reported many times that the person was seen around the village attacking people at night in there homes while they were in bed. Or after the person died an outbreak of a certain disease occured. The only logical explination to people of that time was that the person was a vampire. So during the day, in large numbers, villagers went to the person grave site and dug up the body. Now during those days, medical knowledge was not as it is today and they didnt know much about decomposition. So when they opend the coffin they found that the body was somewhat limber, it had new skin, and hair and nails have grown. There was blood around the mouth and on the shroud. And the corpse was bloated and and warm. Now to those people that looked like a vampire. So they got a wooden stake and drove it through its heart. While doing that, blood shot out and the corpse let out a yell. To them that further showed them that the deceased was a vampire. But with the medical knowledge of today, there is an explination for everyone of these so called "vampire traits". The bloating occured because the microorganisms of decomposition produce gas, mostly methane, and lacking an escape route it collects in tissues and body cavities. This bloating gives the vampire its plump appearance. Decomposition produces heat, hence the warmness of the vampire. Many also describe sounds coming form the vampires grave. These sounds are most likely the bursting of the abdominal wall distended by gas. Likewise when the abdomen explodes, the corpse's shroud is bloodied. What they saw around the mouth is not fresh blood  but frothy, liquified tissue and decomposing blood forced out by the expanding pressure in the body. As for the presence of "fresh" blood in the corpse, blood does coagulate after death, but depending on how death occurd, it could liquify again. Blood tends to reliquify when death has been sudden. That would make people think that vampires are made when death was violent or suicide. And that reliquifying of blood would cause the vampire to bleed when staked. The limberness of the corpse can be explained becuase what we know of rigor mortis is only a temporary condition. The rate at which it arrives and departs is subject to variation, but typically it passes within 36 hours. What seems to be continued growth of hair or nails is really just the natural shrinking back of skin and gums which causes teeth, hair, and nails to appear longer than they really are. This sloughing away of the outer layer of skin is known as "skin slippage". Even the vampires shriek when staked can be explained. This is the noise made when pent up gasses inside the corpse are forced over the vocal cords. This explains most of the encounters of vampires in the 1700's. But this dosent always explain some cases of vampirism, but does explain most vampire encounters.
