IT doesn't seem as if the dog, Ellie is disturbed at all by the orb. So whoever or whatever it is seems benign and pleasant. I think it might just have been a dog lover and wanted to see Ellie. I wonder if the man who died there had a dog?
I still find those orbs quite fascinating. I thought they were portals but I really am not sure what they are. They are different sizes and I wonder what the significance of the sizes is. More that one person in the orb perhaps. Its a mystery still.
