Wave of the Ghost?

Photo date: December 11, 2015. Photographer: Mark Mahin.

The unaltered photo below was taken in Grand Central Terminal in New York, and shows a figure standing on the West Balcony of  the station.  The figure looks almost like some ghost waving his hand.

On the same balcony I photographed the interesting-looking figure below, one that seems to have huge black eyes.

I informally call the West Balcony of Grand Central Terminal "the ghost balcony," because when photographing it from the East Balcony I often see in my photos what looks like ghostly-looking things on the West Balcony.  Below is another example from December 11. We seem to see some weird luminous figures in the middle, with some dark shadowy figures below them.
