Its hard to say, really. I suppose the strangest thing in that regard happened to me as a child. My parents and I were visiting what I think was a Civil War battle site. We were in a large building, kinda like a shop or museum, and I could have sworn that I'd been there before. It wasn't a question of, hmm, have a been here before..it was a certainty. I even mentioned to my mother about the last we were here when she dropped a bombshell on me by stating that we had never been there. It kinda freaked me out at the time, and still does I suppose. On another note, I've always had an odd draw to Europe...Mainly Britain and Scotland...not sure why.
I believe we live different lives. I don't think I've ever had a feeling like that, like I know something from the different life... But I often have this effect of deja-vu. By one of existing theories, when we experience a deja-vu, it means we have already been in this situation in a previous life. I do not know if that is true, but I would not dare say it is 100% impossible I have also read that a person lives through 9 life circles (hey, is it the same as cats?). I have counted mine and it said I am living the last, 9th life... Well, I don't know if we should believe it or not. But what I am sure in is that we do have previous lives and we are somehow learning from those lives. And the person you are now comes from all those lies, everyone gets what he deserves... Where did I get these crazy ideas, I wonder? It's scary...
Yes, I have had this feeling before, and I'm not sure if it genetic or spiritual. Even back when I was in school, a long time ago, professors were talking about genes carrying memories through decendants. When I am in the New England area, it seems familiar to me. I have not visited Wyoming or New Mexico, but when I watch the series Longmire (set in Wyoming, mostly filmed in New Mexico) it also seems familiar.
I don't know, I'd like to think I have. Think it'd be super awesome to find out for sure somehow. If I was, I'm sure I had to have been British, because just seeing pics of the rolling green hills and the rocks and the castle ruins gets me all choked up, and if it's one of those flyover tours they show on PBS set to music (dunno what they call the show, but they show many scenes from around the country, like bird's eye view. They show those green hills, or the cliffs by the sea, and I get tears in my eyes, hard to breathe, like I'm longing to go there with every fiber of my being.
My family is of Irish and German descent though. Pics of Germany don't have that affect on me though. Ireland does in a 'OMG it's gorgeous' sort of way, but not the same feeling like I'm going to cry as views of the British countryside does.
