I know that my deceased husband comes to me on occasion. One day I felt that I needed to clean out some boxes. Every box was filled with greeting cards from him. Boxes of cards in every size and shape for every occasion, he just loved giving them to me. Each card had a few words of love and I was almost overcome with emotion and finally stopped going through the boxes. When I happened to look at the calendar, it was our wedding anniversary. He has done things like this many times, I never see him, but I sense him near. I believe there are auras around people, I believe dogs and cats can see them.
