This is one of many strange and unexplainable occurrences that have taken place at my childhood home. The history of the land on which it stands is rather well known, at this point: long ago, it was a logging camp, a camp for Japanese students, and a Boy Scout camp. Eventually it was purchased by my grandparents, sectioned off into three lots, one of which was bought by my father. This is where my parents' house now stands.
The following is one of the more recent instances of paranormal or unexplained activity.
During the summer of 2009, I was pregnant and temporarily staying with my parents and my two younger siblings. My father was out of town, staying the weekend at my parents' lake house, so my mother and I decided to make it a movie weekend. We rented 'Coraline', got some Chinese food, and started getting ready to watch the movie in our living room. My sister didn't want to watch the movie with us, too busy watching some action movie in her bedroom.
I think Mom must have forgotten something in her bedroom, because she paused the movie before it even started and went into the back of the house. My brother and I were sitting in the living room, waiting for her to come back, when I suddenly heard a piano playing faintly. It was a run of seven notes, forming a melody that I'd never heard before. And it sounded as if it was coming from just outside the large living room windows. I looked at my brother, who looked right back at me, wide-eyed. We both agreed that we'd heard the same thing.
The sound echoed again, although this time it sounded as if it were coming from an entirely different area - beyond the front door, on the complete opposite side of the house. Stunned (and definitely curious), we followed the slow, slightly creepy melody out of the living room and to the foyer.
"It sounds like it's coming from the back," my brother said quietly. I disagreed, insisting that it was drifting away, over the yard and toward the woods at the limits of our property. But as I listened, I realized that it sounded as if it was going... Both ways? The melody seemed to be coming and going from all directions at once.
Our mom came out of her bedroom then, and my brother and I quickly agreed to ask her if she'd heard it as well. "Did you hear that?" we asked her as she walked toward us.
"What?" she asked, "You mean the piano?" Well that settled it. My brother and I weren't just going crazy simultaneously. The three of us searched through the house, trying to find a logical source for the music. We checked music boxes, mp3 players, televisions, cell phones, and of course the two pianos in the house - anything that could have produced the melody. We questioned my sister, who swore she hadn't heard anything over the noise of her movie (we also considered the possibility that maybe we heard her movie, but that proved to be wrong). We couldn't find anything that made sense, and we decided we weren't going to go outside chasing some creepy, invisible music into the woods.
"Must have been the ghost," my mom said, shrugging. We left it at that, and went back to the living room, closed the curtains against the darkness, and continued on with our movie. Nothing else happened that night.
