This isn't a ghost story, but it's a bit creepy.
I grew up on a farm that was being developed into a residential neighborhood. At the end of the new street were several acres of thickly wooded river bluffs and deep hollows. I had a campsite overlooking the Missouri River back there. Because my extended family collectively owned the woods, I could and did build a permanent campsite there and I spent lots of summer days there for years. When I was in college, one of my uncles casually mentioned to me that there were "nine Civil War soldier graves" along a particular fence row. I knew an earthen Civil War fort had once been located in that area and I knew a substantial battle was fought at the fort, but no one knew the precise location of any of this. The story my uncle told me seemed plausible, and he was one of the family who bought the land after WWII, so it seemed logical that he might have received an oral history from the previous land owner. I walked along that fence row to my hangout on every excursion, but I never saw any mounds or any bones washing out, so I eventually forgot about it.
The land got sold, I moved elsewhere in the same town, and decades passed.
I've told this next part in other threads here. A couple of years ago, a family from Illinois stopped by the local visitor's center and asked about the location of the fort. They produced a diary written by their Civil War ancestor who was stationed at the fort, and it included a map of the fort and surrounding key features which identified the location. The Visitor's Center people scanned the map and I obtained a copy. I recognized some of the roads, gates, hollows, and two houses as features of the land where I grew up. I was able to layer all of this over a Google satellite photo and make an exact determination of the size and location of the soldier fort! What a find!
But here's the creepy part: The soldier drew the hollows and the line along which my campsite trail ran. A notation on the soldier's map, right there in the fence row said: "Soldier Graves."
