This dream scared me! Should I call?? My mom has been with this guy since October of 2006.?

He's not good for her at all. He drinks everyday all day and when he gets drunk he goes on these rampages. I've never known of him to hit her. He just throws things and yells and says horrible things. She leaves, but always goes back to give him another chance. She even moved out of state to get away from him and start new. She went back again. She told me if things get too bad again that she will leave. Well, I just had this dream that I went to visit. Everything seemed fine when I went in. After a playing with his granddaughters (there's really only one but in my dream there was another one). After a while, I asked where my mom was. Before his daughter could stop her my stepsister(from my mom's last marriage of 10 years) told me they were outside and my mom had been laying on the ground since he hit her. Anger instantly rushed through my body. I was getting ready to go tell her how mad i was that she didn't leave. I looked out the window and she was laying on the ground.
