Telepathy, by definition, is deliberate transmission of information from one person to another without using one of the known sensory channels or physical interaction.
The adepts of mesmerism are those who have discovered that telepathy is one of paranormal phenomena and have noticed that there are certain people who can read thoughts and "execute unspoken orders."
At first it was thought that telepathy occurred by transmitting and receiving electromagnetic waves, but all attempts to record these signals gave no results.
Other hypotheses have been proposed, but can not be tested. Richard Feynman was of the opinion that these telepathic messages could be carried by positrons (electron counterpart) and tachyons (hypothetical particles that would travel faster than light itself). Freud considers telepathy a kind of "primitive faculty," lost by man throughout evolution. He said that telepathy is only possible between people who have a close emotional bond. Gustav Jung believed that the function of telepathy is a synchronicity and that it influences our dreams.
Wiener, an American cyberneist, believes that alpha waves (at 10 Hz) would actually be the material support of telepathy and that this is only possible in a maximum relaxation state. But psychophysiologists are different. They say that telepathy is a function of the subconscious. As evidence, while electroencephalogram (EEG) is recorded in some animals, and at a great distance, chickens are sacrificed, a sudden change occurs on the EEG.
If we were to take all this information, we can deduce that there are two types of telepathy. The first type is telepathic hallucination, produced in the semi-awake condition when a close is involved in some kind of accident. The other would be the telepathic dream, transmitted by a person in need of help. Statistically, only 35% of telepathic communications are in the waking state, the rest being received in the dream.
But there are skeptics, like Albert Einstein, who said, "If telepathy does not change either by time or by distance - that means it would escape the laws of physics, which is absurd, because everything in this world is governed by these laws. "
