Haven't the foggiest

While checking my hotmail account this afternoon, I noticed an ad for an upcoming film, The Fog. There was nothing particularly strange with that - what was odd was a news piece I had seen this morning about a mystery fog engulfing Lagos in Nigeria. The city has reportedly been enveloped in a thick, white, malodorous fog, causing panic and traffic jams. It is reminiscent of Ladies in Lavendar and the young man with no evident identity being found wandering, mute, on a beach. Life imitating art again perhaps?
