Hi Liah, you have me totally hooked on this conversation! I think I told you about my "dream" - I dreamt that an uncle of mine, who I have never met, because he was MIA in WW2, was in the window of my grandmother's house and called me into the building. I went because he looked like my brother, Danny, to me. I mentioned that to him when I went in and he smiled and told me he knew that all ready, and that he was my Uncle Chas. He told me to please tell my father that he is not alone, that they are all with him all the time. I woke up and forgot totally about it. Later that day, I found myself unexpectantly having to do an unplanned errand which took me past my parents house, and when I was driving by, I pulled over and parked and stopped in unexpectantly, because I just thought I should even though I was rushing to get things done. When I went into the house, only my father was home, he was on the couch, and he was surprised to see me. When I saw him, right away the dream popped into my head, I remembered it in great detail. I told my father the dream and he was so surprised by it, because he told me that he was just sitting here feeling very alone and feeling very much like an orphan because everyone in his immediate family (mother, father, brothers) were gone and that he was just thinking about his older brother Chas, it was 50 years to the day that his plane went down.
Liah, regarding the issue of being somewhere before and seeing something before or having knowledge of it, once again, in my reading of these experiences, I have read the theory that before we all are born in body, that we are all spirits who actually create and have a blueprint for our own lives on earth, we choose our own blueprint and plan as to what happens to us and all have reasons why we chose, to grow spiritually and to learn while here, and that when we have feelings that we saw something or knew something that we haven't, it's just us remembering our blueprints and a sign that we're on the right track.
Don't know about all this, but I'm always very interested to find more information and ponder the thoughts and theories out there.
