The Dream of March 2

Desperately trying to remember details from this one as I found it interesting. I don't think anyone in it was "real", but possibly a few people shared characteristics or appearances with friends of mine. I'm also struggling to remember if the people in it spoke Swedish or English, but I really don't remember that particular aspect.

I was somewhere in the countryside, with a man and a girl who I think were my father and sister in the dream. The other girl and I were both quite young, possibly about ten years old. We were visiting an elderly couple, the man's parents. They lived in a house, possibly with a small farm, in the countryside of a country that... I think either had been at war about thirty, or so, years ago or the people in the area had ties to a country that had been at war slightly more recently. One thing which definitely suggests something had caused the elderly couple to move to a different place at some point was the fact that their son, or my father, I guess he was, spoke with an accent as if the language the rest of us spoke wasn't as familiar to him (we can ignore the fact that no matter where he grew up his parents' first language would've been his. Maybe they both spoke these two languages perfectly and thus the other language had been their first whereas the one we now spoke had turned into a second one for their son?).
The house of the elderly couple was right next to a field, and there was only a dirt road leading up to their house - definitely in the middle of nowhere. But on the other side of the field was another house, one that had been inhabitated by a family with children but then left abandoned. I was told the story of it, but I don't know if they had abandoned it due to a war raging in the country or if they'd gone on holiday to the country they were originally from and then a war had started there and caught them by surprise. Either way, we knew the family had died. And my father had promised us we'd go explore the old house.
Since no one had tended to it in more than twenty years we were told to be very careful as we entered the house, hearts pounding. The ground floor seemed solely devoted to being a kitchen and dining area, and off to the right was a door that opened onto a small, fenced in area that now seemed as if every planted thing there had died - even the weeds. There was a small gate in the fence, which opened directly into the huge field that separated this house from my grandparents'.
As I followed my father and sister out there I looked down on the ground and spotted small holes in the dirt. I voiced my concerns about snakes to the others, but my father didn't seem to hear me. My sister looked scared though. Just after my father had gone back inside a mouse appeared from one of the holes and I shrieked and stomped on the ground to try to scare it away. Then we ran into the house too. We very carefully went upstairs and looked around there too. The whole place was very eery and I remember half-expecting the ghosts of the family to turn up and chase us away from their home. On a table by a sofa and a television there was a huge bowl full of tiny chocolate bars. I remember approaching it to check the expiration dates when my sister grabbed me.
"You're not going to take those, are you? I don't think that's legal!"
"I'm not going to take them, I just want to see how old they are."
But I can't remember actually checking them. The next bit I remember is being inside a bedroom and looking at books in a bookcase. There was a series of biographies about an author I was very familiar with. In fact, my grandmother and I had discussed those very biographies the night before. However, the one book in the series we'd talked about the most didn't seem to be there. My grandparents had now appeared outside the house and it seemed my father and sister had joined them, I was the last one in there. After finding those books I went halfway down the stairs, until I could see them through the doorway, and excitedly told them about my findings. I think I was heading back upstairs after that, but I can't remember any more.

I really enjoyed the mood of this dream, it felt just the same as reading a scary book did when I was a kid.
