Dream of biting, cigarette, mother, apartment

My neighbors across the hall from me in my apartment. In my dream they have a baby about 10-15 months old that is addicted to cigarettes. The baby is somehow in my apartment smoking and I'm about to grab her/him to bring him back home. The mother is there, in my living room smirking and lights a cigarette for the baby and gives it to the baby. My apartment has a different layout that what I actually live in. Entrance door leads directly into a small living room. My old bookshelf on the wall looking to the left if you enter the apartment. On the far left wall and the wall across are two old ratty couches. The neighbors still have the bratty daughter that they have in real life, but also have a cat in my dream that tore open the top of my couch on the far left/back wall and likes to sleep inside the couch. I had to force the cat out and grab him while he is hissing and trying to bite me. I took my had to squish the head to keep him from biting me, and threw him across the room where he ran out.
