"This photo was reportedly taken in Marblehead, Massachusetts, during a seance in a house where a mother murdered her children and then committed suicide.
The seance, coordinated by psychic researcher John Spence, was held in the house after a new resident complained of a ghostly presence and felt influenced to harm her own children. In the photograph there appears to be the semi-headless shape of a woman in a dark dress with a large white bow, as well as and the dark, faint shapes of several children.
There is also quite a bit of light streaking, which is usually associated with a double exposure. Other phenomenon reportedly took place at the seance, including a rug folding itself into the letter W, cold spots, the formation of visible energy orbs and rays of neon blue light, and the odors of ozone and a cloying sweet decay. After the seance, the residents moved out and the house remained vacant for several years."
