A human being who feeds off other humans like parasites are known as "psychic vampires." These individuals are believed to drain the energy and vitality of others in order to sustain themselves.

The concept of psychic vampires has been around for centuries and is found in many cultures and belief systems. In some traditions, they are referred to as "energy vampires" or "emotional vampires." They are often portrayed as individuals who are able to manipulate and control others through their psychic abilities.

Psychic vampires are often described as being very charismatic and charming, able to draw people in with their charm and charisma. They may also be very manipulative and skilled at getting others to do what they want. They are often able to sense the emotions of others and use this to their advantage.

One common belief about psychic vampires is that they feed off the energy of others in order to sustain themselves. This can be physical energy, emotional energy, or even spiritual energy. They may do this through physical contact, such as hugging or touching, or through emotional manipulation, such as guilt-tripping or shaming.

Some people believe that psychic vampires are not aware of what they are doing and may not even realize that they are draining others of their energy. Others believe that they are fully aware of their actions and choose to manipulate others in order to gain power and control.

There is no scientific evidence to support the existence of psychic vampires or their ability to feed off the energy of others. However, some people believe that they have experienced the effects of psychic vampirism and feel drained or exhausted after interacting with certain individuals.

It is important to note that the concept of psychic vampires is often used in a metaphorical sense, as a way to describe individuals who drain the energy or vitality of others in a more general sense. It is not a diagnosis or a recognized mental health condition.

In conclusion, the idea of humans who feed off other humans like parasites is a controversial and debated topic. While there is no scientific evidence to support the existence of psychic vampires, the concept remains popular in many cultures and belief systems. Whether or not psychic vampirism is a real phenomenon, it is important to be aware of the potential for individuals to manipulate and control others for their own gain.
