This is a link to an article out of Scotland about proof (read: Photo's) of the Edinburgh ghost. When I looked at the photo it was a clear example
of the dust particles being photographed.
Anybody from Scotland? I lived in Edinburgh for two years and its got a tonne of this kind of stuff. Best is the medival streets that were blocked up
and built over with people still inside because they had the plauge. One had 600 people still alive in it when they were blocked in. You can go down
there, it's pretty mental.
