I think this theory is so true. After my grandmother passed away, a couple of months later I had a dream that she was at a family BBQ-she opened the door to come into the backyard and I remember being shocked and happy to see her, so ran up to her and gave her huge a hug, and she told me everything was ok, and to go upstairs and go to sleep. Well, here's the REALLY weird part, a week before I had my dream, my brother had a similar dream that we were at a family BBQ as well, except he was inside of the house and he saw her walk by him in the kitchen and open the door to go outside to the back. That's where his dream ended, with her opening the door from the inside of the house, and mine started with her opening the door, but I was on the outside. So, his dream ended where my dream started. I thought that was pretty cool...
