I saw this ghost image in our neighbours window (middle of the frame in dark part of the window). At first I thought it was a smudge on my glasses, then a smudge on the window, but it was neither. In person it appeared to hover in the space between me and the neighbour's window. Not sure how I'd make a diagram of what the light is doing here but it's obviously something to do with light from the white bag doing something with the double glazing.
