My mother in-law passed in 2007. That night I dreamed she was sitting on the chair in my bedroom telling me goodbye. She also told me she was wrong about me and apologized for it. My wife called me the next morning to tell me she had passed away. To this day I firmly believe she was there to make amends.
What a hoot if she made a special trip to see you on the way out to tell you that she was right about you all along?
