Sarah Winchester was trapped in the Daisy bedroom during the great San Francisco earthquake of 1906. When the earthquake struck, Sarah thought the vengeful spirits had caused the earthquake causing her to be trapped to the point of her staff had to dig her out because the entrance was blocked off by rubble. So when she was free she boarded it up and no on has ever set foot in that room until 2017.
Since it has been open some of the guides have claimed to hear heavy sighs and saw dark figures in the hallway. Another worker reported camera malfunctions while photographing the space, while looking over the photos saw some weird white rippling mass.
