It's impressive how the mind looks for human figures in abstract and obscure situations. I certainly can see the ghostly figure in the picture, although it appears to me to be just a trick of the shadows (and it almost appears there is a mirroring artifact to the left of the ghost). It would be interesting to know if the fact we're hard-wired to look for human shapes is a by-product of or contributing factor to us being social creatures. I suppose it could also represent threat detection, but I would think we would be more likely to imagine we see things like large predators in such a case. Anyway, interesting way that photo turned out.
