Pandora, that reminds me, I lived in a town about 30 miles from where I am now. It is a nice old town, but the downtown area is just pathetic -- they have lots of potential for tourism, but the "powers that be" don't want anything new in the area. Anyway, a few years ago, a woman tried to put in an ice cream parlor in one of the old buildings. After a few weeks, they started having a lot of weird things happen. One girl who worked there said when closing at night, they would often hear loud noises upstairs. She came in one day and found all of the chairs, heavy wooden ones, stacked in a pyramid. The woman who owned it supposedly got so discouraged she sold the business. A small restraunt is there now, but I don't know if they have had similar experiences.
Also, the house I lived in, about 3 blocks away, also had its share of things like you described, I had forgotten. Most of it would happen around the holidays. I remember one night mom and I were watching tv and talking late one night when I swore the china cabinet in the next room toppled over. I ran to investigate, and nothing was out of place. Another night, we heard another crash, this one in the living room. Two small figurines were on the floor, intact, several feet from where they should have fallen. Plus, they would not have made the commotion that we heard.
I loved that old house. James keeps driving by waiting for it to go back up for sale. Maybe someday! I would probably give it a good smudging though!
