Psychic vampires often discuss methods of finding energy sources and "feeding" reliably and harmlessly, and these methods vary to a high degree. There are psychic vampires who "feed" during sex, those who "feed" on large crowds, those who draw energy from the natural world and visit parks or wilderness when "hungry", and those who "feed" by finding people in highly energized states and either calming or further provoking them.

Psychic vampirism is largely performed through visualisation and a great deal of practice. One way to do it is to target a person and just visualise energy inside and around them.

It is recommended that the beginner, especially those without a proper teacher, feed from people who seem invigorated or, shall we say "hyper". This is the easiest victim for they seem to radiate energy. After more practice, one can feed off anyone through young children and elderly should be avoided.

It is not advisable that one try to feed off an ill person, extremely depressed person, or suicidal person. They could not only give off negative energy that would hurt you, but it could further weaken and endanger their lives

Find someone who has an abundance of energy. Once you have selected  your "prey" or "source", concentrate on them.

If you must look at them, then do so. If not, picture them in your mind. Imagine their energy coming out of them and entering you as an electric stream. Feel the build up of energy revitalizing you, making you vibrate with what feels like an electric charge, and draw it all into yourself, feeling it invigorating you.

Continue to do this until you feel satisfied but dont leave them overly exhausted or be noticed. If you do not feel satisfied you may need to feed off more than one person.

In the case of two people exchanging energy, the two people will both gain from exchanging this energy. It seems that exchanging energy generally results in both parties feeling stronger, magically, physically, and emotionally.

As you get more practice, you will be able to this from a distance and over the phone. If you have a compassionate heart or a huge appetite, you can learn to feed off a crowd collectively. You can feed from several different people just taking a little from each one, and never getting too much positive or negative energy.

If you can do it, feed from nature when you can't get to people. The life force in nature is strong, although it doesn't last as long as energy from humans; there is a lot of it, and it is usually easily accessible.
