Woodland fog.?
Does anyone remember those Hammer Horror movies, filmed late at night in the woods--Curse Of the Demon, The Creeping Evil, House of Dracula, etc.?? Directors chose the location especially for this kind of creepy effect. I think the man behind the camera unwittingly provides his own rationale, "They can't be [people]--not over the trees!"? Perfect behavior for woodland fog, though.
Now I have Kate Bush's "Hounds Of Love" in my head:? "It's in the trees!? It's coming!!!"
I don't know... if it's a fake, it's sure one of the best I've seen so far.
