Nah, I'm not referring to the Lichtenberg figures (fractal burn marks), though there were clearly a couple of them tossed into the article to confuse matters. The article talks about a number of instances where the likeness of a person was imaged onto window-glass by a nearby lightning strike when they were looking out the window. I'm wondering if that phenomenon could be real, and if so, how. I can imagine impurities in the glass making it sensitive to various things like the massive electron and photon (UV mostly I think) fluxes surrounding a lightning strike, and certainly those can illuminate a person's face at extreme intensity, but what the hell could focus the image?
The broad pattern of independent reports doesn't look like a mass hysteria (there isn't the communication necessary between locations necessary for that), though in a couple of cases you can see strings of copycat reports occurring after an initial report in some locations.
