Exact same dream and reoccurring dream?

So I haven't thought much of this until now but about two years ago when I first started dating my fiancé I'd told him I had a dream. In the dream we were with three kids, two girls and a boy, next to a creek surrounded by trees. We'd never discussed dreams previously and I just told him about it because it was so vivid at the time. That's when he then told me that he'd had the exact same dream from the creek to the children's genders and ages that they seemed to be. I was just wondering if anyone knew what that could mean?

Also, my fiancé used to have a reoccurring dream of green eyes. He knew it was a wedding and always remembered the green eyes but never the person. I'm the only person he's ever dated that has green eyes and he said eventually he realized the eyes were very very similar to mine and that my face eventually became what he could see and remember in the dream where he couldn't remember before when he woke up. I was just wondering why he'd had the same dream over and over for years and finally attached my face to the eyes?
