Deja vu

First one occurred in back in elementary school. I had this really odd and realistic dream that my grandfather was driving me down this wooded highway. We pass this nondescript vacant brick building and he says “That used to be a gunpowder mill back during the the civil war” and then I woke up. I didn’t think much of it until a few days later when my family and I were driving to see a 4th of July fireworks show at a nearby park. I noticed the road we were on seemed familiar and then suddenly I saw the EXACT same building from my dream, surroundings and all. I started freaking out but calmed down once we got to the park. Some other family members were there and when I found my grandfather I asked him if he knew anything about the old brick building next to the road. He told me it was a civil-war era gunpowder mill. I still get chills thinking about it. I have no known connections to this building and I can find hardly anything about it. It is located in the small village of Goes Station, OH.
