The vampire can either come into existence by exchanging blood with another vampire or being born as one(Lamia). Vampires can be killed using a wooden stake through the heart, beheading, or exposure to sunlight.
Another type of vampire is the psychic vampire. This kind of vampire drains its victims of psychic energy in order to live. Most often, the psychic vampire is unaware of its condition and continues to harm thous around it without seeking help. This vampire is basically human and can be killed just as easily.
