Often these individuals are completely unaware of the effect their presence has on others. When they enter a crowded room, the vitality drains from those around them. A dark shadow seems to grip the heart. The psychic vampire may be animated and laughing all the while, but the happiness of others drains away. Usually this type of vampiric personality fixes itself on one person, or a small group, and feeds upon the life force of its victims until its victims are little more than hollow shells.
Vampirized individuals lose hope, lack all energy or enthusiasm, and often commit suicide.
The sucking of the life force occurs during sleep as well as waking. The dreams of the victim are haunted by the psychic vampire. Over time the will of the vampire completely subdues and controls the will of the victim. In this way the victim is prevented from breaking off the social connection with the vampire. As the vampire grows more vigorous and animated, the victim sinks into a dreaming, depressed, listless state.
