Sometimes called "ESP or a sixth sense", Clairvoyance is the ability to see or sense information that is not readily available to them by normal human means such as sight, smell or sound. This extra-sensory perception may or may not have boundaries such as time or place. A person said to have the ability of clairvoyance is referred to as a clairvoyant.

It is differentiated from telepathy in that the information is said to be gained directly from an external physical source, rather than being transferred from the mind of one individual to another.
