When you google what clairvoyance is, you will find different interpretation of it, people that put in the definitions of Clairvoyance are not themselves a clairvoyant. The definition is “a person who claims to have a supernatural ability to perceive events in the future or beyond normal sensory contact” http://www,dictionary.com/clairvoyant
So I will share my experience as a Clairvoyant to give you a better understanding of what it is like and how it feels. For me its images that come to me, whether in a dream, or just comes into my head in flashes. How to explain it better is my clients personal experiences, flash to me then become my memories. I do not see it as their exactly experience, however it will come to me as a message and i will then be able to interpret it to my client.
Everyone’s experience as a clairvoyant will be different, but for me it comes as images, and as dream images. However each person will interpret their experiences differently, some may be able to see a spirit directly telling them things.
