Psychic vampirism as an adult adjustment style usually has a long history in which symptoms, along with related changes in the aura, often emerge in the early teen years. Faulty social learning and unfulfilled social needs are commonly present in the background of psychic vampires. Often because of limited opportunities for social interaction and comparison, psychic vampires develop their won patterns of social fulillment. They begin early to exercise the energy receiving capacity of the aura. As the receiving function of the aura become dominant over other aura characteristics, actual structural changes begin to occur in the visible aura of a psychic vampire.
Among the major aura characteristics signaling psychic vampirism are numerous voids and areas of washed-out or drab coloration along with a shadowy, exernal region. Among advanced psychic vampires, dark structures, sometimes called vampire tentacles, can be seen reaching beyond the area of normal aura activity. Whe preparing for interaction, the tentacles, can be seen stretching outward as if in search of a host victim. Upon contact with the host, the tentacles either interface the aura for a slow absorption of energy or they puncture the aura to draw instantly from its inner energy supply. The effects of the encounter are immediately visible in both the vampire and the host. As the host's aura recedes and diminshes in brightness, the vampire's arua expands and pulsates with new energy.
