Sleep event

This is the first of two dreams that I remember from last night. The first was lucid and the second was not. I forgot the second while writing down the second. (Woke up to <PERSON> stuck in my head. lol) Here is a bit of a back story. I have four younger siblings who live with just my mother at the moment. I am away at college and have not been back for a bit over a year now. My siblings and I have been abused since before I can remember by my mother and her boyfriend. (He got kicked out. He is never abused her, and I think he did recently. He is done a lot, and I think that is the only thing that would make my mother kick him out.) The dream took place mostly in hallways. My sister (who is the second oldest still living with my mother) was getting hit. Then, my mother put this yellow mesh dress over her clothes. (I have no idea why, because it does not relate to the dream otherwise.) I kept going out and coming back in. Every time I went out, I tried to get other people to help, but I could not talk. Then, I was sitting on this really big, hard-wood, sturdily built table. (In real life, I do not think I could get it to move an inch by myself.) I got in trouble for sitting on it. My mother was yelling at me and about to hit me. (There was no sound at all during the entire dream for some reason.) I got my sister to stand behind me, and I picked up the table to use as a shield. Someone was walking by, and I managed to yell for help after a few tries. I realized it was a dream somewhere around the time I was lifting the table easily and when I could speak. I was able to speak and hear sound for the first time when I realized I was dreaming.
