This is called a Channel. They learn to work with a variety of frequencies.

Clairsentience

      A person with clairsentience is able to gather information merely by touching an object or person. It is said that they are able to feel the vibrations of other peoples' moods. They can pick up diseases that other people have, and rather than developing an actual picture in their mind, they form a vivid feeling based on what they gather from the person or object they had touched. Clairsentient is feeling. Through clairsentience one can feel or sense a presence, for example or feel emotions or pain.
In the field of parapsychology, clairsentience [From the French clair, "clear," + sentience, "feeling," ultimately derived from the Latin clarus, "clear," + sentiens, derived from sentire, "to feel"] is a form of extra-sensory perception wherein a person acquires psychic knowledge primarily by means of feeling. In addition to parapsychology, the term also plays a role in some religions. For example: clairsentience is one of the six human special functions mentioned or recorded in Buddhism. It is an ability that can be obtained at advanced meditation level. Generally the term refers to a person who can feet the vibration of other people.

Clairvoyance is the art of 'seeing' beyond the five senses. Clairvoyance is often called the 'sixth sense' or ESP. It is related to the images that are always present in our minds that bring messages from other frequency and realms. These images can be archetypes, colors, still frame, animations. They can be anything. They can remain on a few seconds or much longer. Initially its easiest to see them with your eyes closed. As you develop your psychic abilities will be able to look to higher frequency, with your eyes opened.
In clairvoyance we 'see' with what is commonly called the third eye. in the human brain there is a gland called the pineal gland. It is located in the back area of the brain almost in the center of the head. This gland has degenerated from its original size comparable to a ping pong ball to its present size comparable to a pea, because we forgot how to use it a long time ago when our breathing patterns changed.

Claircognizance

Claircognizance is the ability to know something without knowing why or how you knew it. It's like something randomly appears in your head, and you don't quite understand how it got there.

Initiate your skill of Claircognizance. .......Have faith in what you see.......
For claircognizants, their higher self or spirit guides put information (in the form of thought) into their mind. This can be a whole load of information that is 'downloaded' into the mind. It can be smaller insights about people and situations here and there. It can be an inspired idea. All Claircognizance is characterized by this strong sense of knowing that goes beyond logic and by the fact that the intuitive information comes into the mind, not into the heart or the mind's eye.
