Some even take it further to say that not only are we around the same souls as we've always been, but that we actually choose who we'll be with and what the cirucumstances are going to be in order to learn, and to evolve our spirits. I've read that when you have that feeling of deja vu, it's because, yes, you have seen it before - you were shown it before you were born!

Now many think this is complete hogwash and ask why we would ever subject ourselves to some of the awful things we find ourselves living through. I don't know. But it is interesting to think about...
When I was 19, I'd just moved out of my house, started college, began a new job, and the furthest thing on my mind, truly not something I
ever thought about at that time - was marriage. (I was going to be a "career girl".) Meanwhile, I met a great guy and we became fast friends; seemed to have so much in common, basic values and stuff; felt like I'd known him forever. One day as he was walking away from me going home, I found myself standing there crying, sad that he was leaving, and heard my inner voice say, "I could marry that guy".

Huh??
What did I just say?? 
Well needless to say, we've been married for 21 years, together even longer. And I can't imagine my life without him. I actually told him this story (I believe for the first time) recently, after reading those books I mentioned above. I don't completely understand it, but I do believe it was destiny, and he agrees.
