I've always been fascinated by zombies ever since I was little and my grandfather died of cancer. I dreamt of him one night and he appeared to me as a zombie... walking slowly, always behind me. Every time I turned around he was there... following me. It appeared that he never lost ground as there was always the same distance between us.
It was a pretty creepy dream. Especially for one so young. Since then, and my brother's passing, I have dreams with him as a zombie. He never talks to me, however, he never tries to attack me either.
It isn't very often. I had the one of my grandfather and three with my brother. I hope that one night, one of your loved ones will stop by to let you know that they are thinking of you.
