Notice the blue lightning-bolt-like line dissecting the photograph.  The senior NEPRS Medium has reported spectrally seeing this type of phenomenon  before and that it generally begins as a line of light, then open into a wide veil or curtain of light phenomenon.

   In photo # 2 (above) we see a curtain-like light phenomenon of blue cascading light against the backdrop of a dark forested area.

   In photo #3 (above) the blue light is still visible but is less apparent  in the left, middle area of the photograph.
