Clairvoyance, based on a 17th Century term meaning clear vision, is a kind of ESP - Extra Sensory Perception. Although often used to describe many different psychic abilities, for example second sight, telepathy, prophetic thoughts and psychic dreams, it is strictly speaking the capability to discern information regarding a person, object, location or event via perception other than from the usual five feelings. A person gifted with this ability is called a email - a person who recognizes clearly.
In parapsychology, the phrase clairvoyance is used purely to spell it out information - in the the present time and not necessarily readily accessible to the particular clairvoyant - caused by an external source, as opposed to telepathy, where information is transferred from one mind to a new. In other words, a clairvoyant has the ability to see or visualise events, things or persons outside the capability or array of physical sight.
Remote control viewing, usually a controlled, specific process, is really a facet of voyance gratuite, as is clairvoyant dreaming. For instance, chances are you'll dream about a location they have never seen before and then find it is exactly since they had visualised it in their dream.
This became of me, for example, after i was about to start my personal first term at school. As I had never visited the city where the school was located, my dad offered to take me there in order to find just how from the train station towards the college. Having dreamt about it the night prior to we went, I had been able to lead him to the faculty along the shortest route possible, knowing in which and when to turn. I was even able to tell him how long it would consider us to get there.
However, outside of the field of parapsychology the term is often used to describe other types of paranormal, or anomalous, perception. Most of the time, it is used in relation to its the perception of earlier (retro cognition) or future (precognition) events. This is a gift many have without even realising it. To use another personal experience as an example (and I do not claim to be a email in any way), a few years ago, any friend's daughter choose to go into hospital at the start of the evening to have the woman's first child. While with a group of common friends around 10 PM, somebody suggested we should call the hospital and find out how she was making. As one of them picked up the phone, I announced that a call could be wasted, as she had have a little boy during the early hours of the following morning. We referred to as anyway and were advised she was in bed as the labour had slowed. My friend explained to me the next morning in which her grandson was born at 5:30 AM.
Frequently, mediums will also refer to the perception of images perceived during communication together with spirits as clairvoyance.
Regardless, clairvoyance is a precious reward which can and should supply in order to help and guide others.
