"The vampire drinks the human's blood and, usually not consensually, induces the human to drink their blood in return. The human dies; their body undergoes a period of extremely corpselike dormancy ranging in length from a few hours to a few days, and then rises as an only moderately corpselike vampire. Opinions vary on whether or not the resulting vampire and the original human are the same person, but there are noticeable personality changes in every case."
