Feeding Techniques will vary depending upon things like the needs of the Vampire, the comfort level of Donors, etc.
Psychic Vampires can feed either through touch or through strictly psychic means, pulling energy by force of Will. The nature of the touch and psychic method used depends upon the nature of the Vampire and the boundaries agreed upon between the Vampire and Donor.
Feeding techniques for other types of Vampires have already been explained or implied in the
Vampire Types section of this site.
Ultimately, it is the Life Force that Vampires feed on. This is true whether it is absorbed as Ambient Energy, or through Sexual Fluids and Orgasm, Blood, etc.
Vampires can also heal a variety of illnesses, because they can remove blockages in the life force by being very selective in exactly where they pull energy from. Though there are many systems of healing, this is a method that vampires can use to be of service to others.
The most ethical ways to feed are through Ambient Energy and through consenting Donors. These are the methods that will be discussed on this website.
Ambient Energy is energy that is generated by humans, but is not directly attached to them. A good example is rock concerts and sports events, where people are frequently cheering or otherwise very emotional. Other good places to feed are shopping malls and places of this nature, where there are frequently large numbers of people. There is enough free flowing energy here for Vampires to feed on without taking it directly from other human beings.
