I believe...have had several experiences but never actually saw one. Smells, strange happenings, etc. My daughter has had things happen to her such as when she walked into our church when it was empty to plan her wedding decorations and distinctly heard her grandma say "Well, hi there sweetie." That was her pet name for my daughter. Also, one day my daughter and I were talking on the phone and talking about memories of mom when all of a sudden my daughter exclaimed, "you're not going to believe this...the rocking chair on the other side of the room is spinning around all by itself!" I think it's comforting to believe sometimes.
