What are robbing dreams about?

This is from a couple of years back. Any ideas? As a note I have no kids and have never been pregnant.

Dream:
The dream begins as I am giving birth. I am in the bed in the room I slept in as a teenager. My mother and sister are there delivering the baby. As soon as the birth is over I am exhausted and fall asleep. While I am sleeping, my mom and sister discuss who will have custody of the baby. In the dream world it seems to be a given that I am a mad woman and am not fit to care for the child. It is decided that my mom will be the baby's mother.

She takes the baby to her room and feeds him a bottle. Then she leaves the house to buy him a cradle at bed bath & beyond. 

While she is out I wake up (in the dream) and notice the baby is missing. I immediately understand what has happened and go in search of the baby. I find the baby and somehow know my mom has fed him. This fact really upsets me. I know that I shouldn't have the baby since I'm crazy but I decide to steal the baby back anyway.

The dream location shifts from my parents house to a dreary hallway in what looks like a school/community center. (Grey linoleum, Drop ceiling tiles, etc.) I am trying to find someplace to go. I look into the windows on each door in the hallway No place is right. My baby is crying and hungry.

Finally I find a room and decide it will have to do. In the room are groups of young men, religious students studying Talmud at tables. They are focused on their studies and don't notice me. There is a screen room-divider between the door and the larger study hall forming a small antechamber which gives me a small amount of privacy

I don't want anyone to see me and know that the men will easily spot me if they turn around but decide that I need to feed this baby no matter what and to hell with what those men think. I lift my dress exposing my entire lower body. I stand there immodest and defiant and nurse my baby when all of a sudden my sister bursts in. She has been frantically searching for me. She is worried about the safety of the baby and is relieved to see that I haven't done anything too terrible (although she is scandalized at how exposed I am). She puts her arm around my shoulder and leads me back to my parents house where I will give up the baby.

So me and my boyfriend were planning on robbing a bank together, but the bank was also combined with a sheriff’s office. So my job was to distract the sherif while my boyfriend stole the money from a safe in a back room, but it was only me, the sherif, and my boyfriend in this building. No one else.

I remember this sherif had glasses and a long thin brown beard, and he really (and I mean really) liked mattresses. Not in a sexual way, he just liked mattresses.

So in order to distract the sherif, I started saying, “what would happen if you put a king sized mattress onto another mattress? Would it be mattress squared?” As in the math term. And this blew his mind.

We escaped with the money, but “mattress squared” will always make me giggle. Any interpretations?

I dreamt that I saw a trendy, expensive vase it came into my possession. It belonged to my sister in law (which had been given to her by her mother). I loved the vase and considered it expensive. I wanted to keep the vase and not return it or tell her I had her vase. Basically I wanted to keep the stolen vase. Any interpretations?

Such a bad dream. I was at the river, there was an event going on with a ton of people. A kid came up to me and showed me their guinea pig, which I played with for a while. Then I had to leave and the kid traded for their pet tarantula. As I held it, I just thought it was the cutest thing ever. When I got home I put it in the aquarium (where another tarantula lived but for some reason I thought my bf had let it out to wander around? Idk). Then I realized both tarantulas were now in the aquarium and I felt a sudden panic, cause I knew my bf's tarantula was hungry. Before I could save the new spider the other one was doing her happy dance (that she does after she eats) and she attacked. I watched in horror as she killed the other one. They didnt even fight, she just pounced and sunk her fangs into it :( at one point they were both wandering around and I was like oh thank god, I gotta get it out. Then it was as if she had dialogue and I could hear her say, I thought I killed you, and knock the other one down and "stab" it with her fangs. I just thinking omg I'm gonna have to replace this kids spider.

Anyway then I woke up feeling horrible and uneasy. There was more to the dream, including a large man stealing a lot of stuff from the people at the river, and when I told him "fuck you" he said a really funny comeback about me not being fuckable. I wish I could remember it exactly.

Thanks for reading, just wanted to jot this down lol

Twice now I’ve had a dream where I was driving and I get stopped by a group of men, told to get in the backseat, and they steal my car while I’m in it. So kind of a kidnapping? And last night I had a dream where I remember locking my car before going into the gas station to find that it had been steal in the five minutes I was inside.

I don’t know what this sstealcar theme is lol
