I had a dream several weeks ago about one of the greys here on GT and I watched him cross. I let his mom know that I dreamt of him and how much he loved her. (turns out he did actually cross that night I dreamt of him).
Then in my dream, I saw my houndie as a very old senior who curled up and very quietly passed away BUT as I watched her fade, she got smaller and younger until she was a tiny puppy. In that dream, I knew she was telling me that even when she left me physically, she would always be with me, even if in a different form. She then showed me one of my new houndies, and that would be a big white male with a few black spots. I would know him because he would recognize me, and run to me and place his head in my lap.
It was SUCH a vivid dream. All of it.
