That's really interesting as an observation, I have always wondered how these things affect people but surely they can be used for good if you can tap into that energy somehow? I know very little about it.
Your photos are wonderful and it looks like it was a great day.
I believe they can be used for good but our knowledge of this is still being remembered, so it is difficult to find information on it. One of the dowsing ladies I follow on YouTube described how in the old days we would bury our dead on intersecting lines as a way to keep their souls present in the area even after death protecting the village from unwanted souls and dark energies. She says she very often comes across souls who are still trapped in areas where the people have long forgotten about them. It is her job she says to release them so they can continue on the natural cycle of re-birth & death.
