Dream of kitten, space, talking, vehicles, walking, big, children, house, way, dog, man, saw

I dreamed I was in house with really big rooms and outdoor space. In another room was an individual that lives in another town that I knew. In waking life I discovered he was abusing children and brought it to the attention of authorities. He had a website about it and I passed it along. I havent spoken to him in years. In my dream there was a lot of people around and he was in another room. There were a group of guys in the room and one was having a discussion with him. It seemed like a difference of opinion and the man he was talking to turned into a dog, a border collie, right after the transformation he killed the dog. I was in another room but saw this as did others. People not wanting to draw his attention were making movements to leave. He saw this and started to walk towards everyone like nothing happened. As he walked towards people he was walking away from a puppy and a kitten. As the group, myself included, walked away from him he was walking with us talking and sounding off. We were on our way out and his discussion was weird we got outside and got into our vehicles and left leaving him behind
