Hello, IA.

Again - I see no hint to any foul thing going on with that Alsatian dream. First of all, the man is having his elemental under control, not yours. It looks more like he's showing to you what an under-control elemental looks like. As I said, I know the Alsatian as a shepherd dog. The role it is bred and trained for is to be useful to man.

There remains the question of why your response is fear and worry. You gave the explanation yourself - you referenced the events in the past. It doesn't seem like the dream pertains to those events in your past, rather that you have still some fearful reactions because of them.
