Seemingly Silly Dreams

My great-grandmother was a psychic (for real), somehow it's kind of passed down the generations, but on my end it's very "watered down". I only get these feelings in my dreams... A good example:

A lot of the times I'll dream about silly things, like conversations or events that haven't happened yet. Many years ago when I was a teenager, my family and I were living in FL at the time. I had a dream that my mother and I were driving down this one particular road near us and she told me that my father had gotten orders to move. It was very detailed, I even remembered which particular outfits both of us were wearing and how the conversation started.

About 2 weeks after this dream, we were driving down that road, when the conversation started exactly as it did in my dream, I realized we were both wearing the same outfits as in the dream... So I knew what she was going to say next. After she told me, I said, "I know, you told me 2 weeks ago", she promptly replied, "He got his orders 2 days ago there's no way you knew 2 weeks ago".

I get lots of things like that. I've also been dreaming of this man for about 4 or 5 years. I've never met him before, but I could paint a detailed portrait of him (which I've wanted to do for a while, but I'm kind of afraid if I bring him into the real world and he does/doesn't really exist, it will cause me to stop dreaming of him). I'm 99% sure I've never seen him in real life because I think I would remember someone as attractive and distinctive as he is (and probably would've made a spectacle running into a pole or something). It could be one of those astral projections and he just happens to be in there. I only know that he usually has some piece of advice or something important to say and I only see him when I'm in the deepest of sleeps.

What I'm really curious about is if 1. He's a real person 2. If he communicates with me on his side in his dreams in the same manner that I communicate with him in mine. Any thoughts?
