Psychometry is the ability to read the history of or gather feelings from certain objects by holding the object in your hand or placing it to your forehead. Usually small personal objects such as a watch, ring, key or other personal objects are the best.
People with the ability to divine this way are called Psychometrist. The term psychometry was invented in 1842 by J R Buchanan.
Buchanan experimented with some students from Cincinnati medical school and found that when certain students where given an unmarked bottle of medicine they had the same reaction as if they had taken the medicine.
Buchanan developed the theory that all things give off an emanation of energy.
He, as well as others, believed that these emanations contained a sort of record or history of the object. Buchanan believed that objects recorded senses and emotions and these could be played back in the mind of the psychometrist.
Some theosophists attempt to explain psychometry in terms of the Akashic records. Psychometrists usually display this form of divination while in a completely normal and lucid state of mind.
In other words there is no preparation nor any trance-like state needed to achieve the desired results.
Psychometrists are sometimes unable to hold certain objects because of the energy given off by those objects. For example if the object had been used in a violent crime, the person may experience violent visions or feelings associated with that crime.
In some cases if a psychometrist has been handed an object of someone who recently died of illness, he/she may suffer short term symptoms of that same illness.
Psychometric impressions may come in the form of emotions, sounds, scents, tastes, single images, and even visions.
The visions are usually very rapid in nature. The visual images occur with no logical sequences.
Psychometrists usually experience a loss of energy and an increase in body temperature when utilizing their gift. Some report an irregular heartbeat, sweating, lightheadedness, and nausea.
It is generally thought that psychometry is a natural power of the human mind, but some people believe that it is controlled by spiritual beings. Some psychometrists feel that they act as merely an instrument and that its spiritual forces that actually provide the information they gather.
