I often have very similar dreams. Dreams that I am in my old house, or in the driveway of my old house. Dreams that my parents are still together and in the house. (They divorced when I was 17). The most recent dream, just a few days ago, I was in the driveway and a bunch of random people from middle and high school were there with a large truck. I've actually had several variations of this dream before. At least 3 times that I can remember.

Now that I think about it. I can't actually remember the last time I was IN the house in any dreams. Just in the driveway or in the street out front.

Definitely unresolved issues surrounding events or time spent while living there. But I'm not sure why I'd keep dreaming about being in the front yard?? Especially the dreams about being in the front yard surrounded by people, most of which I was never "friends" with, and for the most part felt like an out-cast around.
