ESP stands for Extra-sensory perception. This term is used to describe a means of getting information from a source other than the five human senses. The five typical senses are feeling, hearing, seeing, tasting and smelling.
 

There are various tests that are used to determine if you have ESP, telepathy or are psychic.

Psychics and mediums use extrasensory perception. This is how clairvoyants, psychics and mediums know secret and private information about another person's life and are able to advise them.  Some of them discovered that they had the ability at a young age and some not until later in their life. But they all have one thing in common. They made a decision not to ignore it, but rather to improve and cultivate it through patience, practice and effort. Many people can now benefit from their diligence and persistence.
