In September 2010 I bought a house in a suburb north of Boston. The gentleman who I bought the house from had built it in 1948 and had lived there since. The house was sold because he was in his 90's and could not live on his own any longer. His wife had passed away a few years earlier.
The house was well cared for although aesthetically outdated. The first floor which consisted of a kitchen, dining room, living room, bathroom, and master bedroom was circa 1980. The second floor had two small bedrooms. It was obvious from the wallpaper the last time these bedrooms were decorated it was 1960 something.
On my first day as home owner I started making changes. I pulled up the rugs in the living room and dining room, removed the fake fireplace from the living room and took down all the shelving on the first floor. On the second floor I went through the closets. I found old baseballs and books. From the looks of them they had been there as long as the wallpaper.
Now that I was done clearing out the house I began painting the dining room. I completed one coat of paint and began cleaning up. I was kneeling down with my back to the living room. I stood up and turned around. As I looked into the living room I stopped. I could not believe what I saw. There was a long oval shaped orange light floating in the middle of the room. It was there for a few seconds before it moved towards the bedroom and disappeared. I wasn't scared but shocked by what I saw.
I checked both the living room and bedroom and tried to figure the source of the light. When I couldn't I finished cleaning up and left for the night.
I returned the next morning and resumed painting. It was lunch time when I completed the second coat in the dining room. I was in the bathroom washing out the paintbrushes when I heard above me the sound of marbles being dropped one at a time on the floor and rolling across it. I stopped. Turning off the water I sat on the side of the tub and listened. It happened again. This did scare me. I didn't investigate this time. Instead I quickly finished cleaning and left for the day.
This was the first of many experiences in my house.
You said that the old man's wife died a few years prior to him selling the house, and that he built it himself, yes? Maybe this was his wife letting you know not to make too many changes. After all, it was their house first! 😆
