Was going to edit but it's been too long, went to make a coffee, so will add more now.
I always get this feeling like my fiance and I have known each other before. And I don't think it has anything to do with him being my fiance. It's something else. I met him when we were in middle school, not even teenagers, and I always knew there was something different. Always knew we'd be together. We broke up after highschool and he moved away, and then 6 years later ran into each other by accident and got back together almost immediately. But something in me just says that we've been together before, more than once. It's a feeling I cannot describe and likely anyone I've ever told that to thinks I am crazy without a doubt.
I sort of feel this way about my younger mare too. Before I first saw her, when I was very young, I always had dreams about a large bay mare with stockings and a star on her forehead, and in my dreams I always had this idea that she was "17.2h". When I first saw her add, there were no pictures posted, and she was described as a "bay mare, 16.3h". I went out to see her, and there was the star and stockings I'd always pictured. She later grew to 17.2h (I always say she's 17.3h as she's just the slightest hair under). I've had random people over the 6+ years I've owned her comment how she seems like such an old sole. I feel like I've known her before, whether she was mine or not, I just know that I've known her and she likely meant something to me in a past life to have so many dreams about her, not just any bay horse with stockings, but I feel like all the dreams I had were 100% her specifically.
