I recently visited Plymouth, Massachusetts and as a history teacher was excitingly taking photos of everything around me. My friend and I decided to take part in a ghost tour for kicks. The tour took us around town, telling us different ghostly stories and encounters.
Just as the tour was starting we were heading west-ward (away from the ocean, and if I remember correctly down the same street as our meeting place by Plymouth Rock-- I figure from looking at my map, it was North St.) I saw this house on the South side of the street, with it's lovely American flag under the window and took a photo as we were walking by. I was simply interested in the architecture... the tour hadn't even really begun yet and no one was taking photos (since we hadn't arrived at our first haunted location). This house was completely dark, no lights were on inside, and there was nothing in the windows when I took the photo with my digital camera. I always check how the photo came out in case I can do a quick deletion, and noticed the white spot in the window. It was definitely not there for me to physically see in person, but it was in the photo.
When I got home I blew the window up and I think it looks like the face of a woman, with her hair in a bun. But it could be my over active imagination. I don't know the story behind the house itself... but Plymouth has many ghostly stories, so who knows? Zoomed image below
