House of the Seven Gables, Massachusetts
The original house was built in 1667. Over time, the occupants of the house died. The new owners started to renovate some parts just to make it look the same with the original design. Right now, it was already transformed into a museum. Staff and visitors have confessed about experiencing supernatural phenomena while inside. For instance, plumbing and electrical systems seem to act on their own. They turn on and off even without being touched. Shadows of old women and a boy can also be seen constantly inside the house.
