Another disturbing dream

[fbhjr]

I went back to visit the house where I grew up. I had been bought by a family with a husband, wife and young son who was no more than 10.
I don’t remember why I was going back to see the house, but they let me in and showed me around.
At some point in the evening, the wife had to go off somewhere. Their son walked with his mother out to the car to say goodbye.
When he came back in, his father was very angry.
“I told you not to go out when it’s dark!” the father shouted.
“I was just going to the car with mom,” the boy said.
The father grabbed the boys hands and twisted them around in front of him. He then picked the boy up and threw him at the stairway. The boy hit the banister hard enough to break it. He lay there amongst the broken pieces of railing and didn’t move.
“What are you doing!?” I shouted.
“He has to be taught a lesson!” the father shouted back at me.
I took out my cellphone.
“I’m calling the police and an ambulance,” I said.
“NOT IN MY HOUSE YOU’RE NOT!” the father shouted.
I walked out and stood in the front yard and dialed 911.
“Emergency services, how can we help?” the voice on the phone said.
“I just witnessed some domestic violence and a young boy is very hurt,” I said. “I need you to send medical help and the police.”
“What is the name of the offender?” the voice asked me.
I realized I had no idea what the father’s name was.
“I don’t know their name,” I said. “But, I can tell you’re their address.”
I looked up at the house and realized the number on the house was 39 ½, not 57 as it had been when I grew up. I hoped the street name had not changed as well. I walked out into the street to see if I could see the sign, but couldn’t.
I gave them the 39 ½ address and they said they’d send someone right over.
Dream Ends

This one really bugged me a lot. I have no idea what it is about. My father certainly never did anything like that. Nor can I recall ever having seen anyone do that to a child.
Despite the house number change, it did look just like my parent’s house on the in and outside. The furniture was a bit different inside, but the walls, doors and stairs were all the same.
