Quite a few of us have experienced deja vu while running into someone or a place and just for a moment or a long pause we have a inner knowing that you have awareness of events or people that you have never met in this life time. http://en.m.wikipedia.org/wiki/D%C3%A9j%C3%A0_vu
While being in a physical body we can go into the spirit world an experience deja vu experiences also because last night I was in the spirit world and I was on a light road that led to a house and there was trees and pastures around in a country setting. Even through I have no memory of this place I had a inner knowing it belonged to me. It is a place I go for peace.
