What are student dreams about?

Tonight I dreamt that I (+ around 7 other people) went into a elementary school to kill the students and teachers. This all happened under my moms request and order. Her request being to kill everyone on the 1st and 2nd floor, and that’s what we went on to do...
We “successfully” kill about half of the 1st floor, me being responsible for 5 deaths...

At the end, I couldn’t kill my favourite math teacher... I continued talking to her, until she saw one of the bodies. Then I ran.

My real self some how controlled and told that I need to tell that I can’t continue this and quit the dream...
So I went up to my mother told her that I cannot do this, I can’t kill anyone else and that I regret even killing the ones I did. She swore at me for a second.

Then I woke up...

This is totally an unusual scenario and I just want to know, what could this mean??

(I apologise for my english.. It’s like my 4th language so...)

Ok so in the dream I was asleep and I was awakened by a horrible feeling in my stomach. For some reason I brushed it off, even after noticing blood. It wasn't until later that I realized the people I was with had shot me. At that moment I was in a restaurant looking place but it was actually a school cafeteria and made entirely of wood. At that moment the intercom activated and started saying something but the students were too loud so the teachers quieted them down. The intercom was simply speaking gibberish in a monotone female voice. But it was getting faster. For some reason, there, I had a panic attack while everyone was just wondering what was wrong with me for panicking.

What the heck does this mean?

In real life we were classmates but didn't really interact with each other.

I was in med school then I entered this room and noticed it was a waiting room with some patients waiting, I glanced at the doctor in white coat and it was my crush (he was just a student, just like me), I started flirting with him then he gets touchy with me, I got scared someone may see us and I was surprised when he closed the door to give us some privacy, I didn't even said anything to him but he intuitively did that. I was so happy, then he started to undress me kissing my breast, I kissed him lightly in the lips then he said I should have kissed you a long time ago, I was on top of him when we had sex (when I woke up I was confused af that I was the one on top). Then 2 girl classmates barged in throwing us clothes, I immediately knew he was needed at his job so we hurriedly put on our clothes. He got out of the room, and after he returned to me, he gave a red soap, then asked if I'm done dressing. Then it ended there.

It continued on when we were going home, we were walking on the mountains and he was angry, I'm just following him then he asked me what food do I want to eat, I said rice soup. I was starting to get angry too because the way was so rocky and it was drizzling so I have to be careful. When we get to the food place, I was impatiently waiting for the server to approach us. A middle aged woman came to our table and my crush greeted her warmly like they were aquiantances but she's playfully angry at him then I thought he's a regular here so they knew each other, I waited for him to introduce me to her but he didn't and didn't think of it much after he ordered. When we ere waiting for our food, he gazed at me lovingly, sat beside me and started to massage my back. The dream ended there, when I woke up I was frustrated at what happened next.

Does this have any meaning?

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.

before we get into it, i understand this sounds like some dumb dream but it's left me feeling so weird and i can't explain it.

so back story:

i left my school nearly 2 years ago to go into private education. during my whole school experience and even now ive never liked people my age and have always been attracted to older men eg my teachers. (dw nothing ever happened, it was very one sided lol.)

anyways there was this one teacher who i really liked, im gonna call him mike (not his real name ofc). when i left school i never saw or spoke to mike again and it been that way since.

so onto the dream:

basically from what i can remember i was sat on a couch in some room in school which was full of students and teachers. mike entered the room and asked if he could have my seat and for some reason i said no. he then tried to take it from me so he basically ended up jumping on me, to which i grabbed his trousers and then they fell down which exposed his underwear.

then i woke up feeling really upset?
it's been on my mind all day and whenever i think about it i feel super sad.
i haven't thought about mike since i left school and now i deeply miss him? does anyone know why or what it means? thank you!
