It's very possible. I am a firm believer in the Supernatural too and know that animals are very sensitive to spirit activity. Much more so than we are.
There is probably a spirit present. We had a dog, that was one day sitting by me on the couch and she then out of no where started barking and growling and then chased something to my kitchen. It was scary.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
