I have a theory about dead loved ones.
Fortunately I have not lost anyone really close to me. I still have all of my Parents, Grandparents, Aunts and Uncles so I have no personal experience with this.
My theory is that after a loved one dies, they WILL visit you in a dream. I have tested this with a lot of friends and family members and they have all had this happen to them.
My Girlfriend, Sarah, has dreams once a month where her Great Aunt Mary, who she was very close with, visits her. Sarah explains it very well. She says it always feels more real than your normal dreams. She also says that they will converse and at the end of the dream they always say bye to each other because her Aunt says that she "has to go away". Sarah, always wakes up very emotional after dreams like this.
Now here is where the discussion comes in.
-Have you experienced this personally?
-Do you think this is just memories coming alive in your dreams (like most) or do you think this is something more?
Another thing to note, in Sarah's dreams with her Aunt, she is always with two white Husky dogs. Possible spirit animal? Let us know if your dreams about past loved ones include an animal.
And let's keep this discussion free of religion if we can unless it is an important part of your story.
