"Weird Alien Head" Apparition Next to Something Just as Weird

Photo date: December 28, 2015. Photographer: Mark Mahin.

The very strange photo below was taken in Grand Central Terminal in New York.

In the middle of the photo we see something very bizarre: what looks like a weird giant dark triangle (formed by human bodies?). What is that on the right bottom of the triangle -- some type of ghostly figure? To the left of the very odd triangle, we see what resembles some weird alien head with a long chin. Can you see its eye on the left?

What is very odd is that some parts of the top photo look very normal, but other parts look shockingly strange.
