Spooky Unexplained Manifestation Captured on Video | NWT | Norfolk Walks

While I was editing a video I noticed this strange and spooky manifestation.
I am unable to explain this, any ideas?
This video location is the Norfolk Wildlife Trust reserve at East Wretham, part of this site was a grass airfield during WW2, there is also an ancient trackway that runs through the middle.
