Recurring dreams of my brother?

For the past while, I've been having dreams about my brother threatening to kill me if I didnt do something. Then he'd go all slow mo and be slowly pushing a knife towered me while holding me against a wall and I would try to push him away. And last night, he threatened that he'd kill my friends and me if I didn't do something. And he'd push the knife I'n slow mo again. Then, I was on the couch, and my mom and my brother were there. I told her what was happening. And all of a sudden they were on the other couch and she looked like she was beating him. I SWEAR my subconscious is trying to tell me something. PLZ help?? T.T
