the direct line is normal for lens flares.

Its just normally lens flares are in brighter environments. But bright is relative.

they all seem to be in a direct line too which isn't a normal thing. I have given up on orbs because they re easily explained.

This one is interesting...
At first I was not sure what it was until I really pumped up the detail.



You can see the multiple circles which are in a semi-linear pattern. Although the light levels are low, this is still a lens flare. Most likely caused by some low level lighting near the bottom or bottom left of the image.

I'm assuming the objects near the bottom are grave markers.
