What are prom dreams about?

I literally just woke up from a nightmare, and I’m still quite freaked out. I was at school at Prom, wearing a white suit which I had gotten mud on accidentally. A man and a woman, the man with curly hair and glasses, the woman with dark red hair, started rounding everyone up, explaining we would be sold.

They said we would have to be blindfolded for two months, for whatever reason, and I took off. I tried to jump over a fence into a neighbouring houses yard, but the man had beaten me to it. He was taunting me, slowly making his way up to me. I started talking about my family, my brother and my cat, my mum and my dad, but he would not listen.

I was dragged along with the other kids up the school path to the front. We were told to pile into a large white van, which was parked just outside the school. I remember taking off with my friend Tom, who was saying that he was going to crack his head open on the path and kill himself before they could get to him, but I grabbed him, breaking down the door of yet again another neighbouring house. I went inside, gathering as many people as possible before locking the doors, calling 111 (I live in New Zealand) I don’t remember anyone answering, but hearing a large explosion outside. The kidnapped had driven off the road, effectively killing himself and his partner.

For the record I am a senior in high school. I was back in first semester of my senior year in high school and I was trying to flirt with This girl named Alyssa(not real name). And I did a lot of stupid things but eventually we got to the point where we were good friends. I decided I was going to her ask her to the prom the next week(today was Thursday). And then someone came in and said that they wanted volunteers for some sort of science experiment. Alyssa raised her hand, so of course I did to. They asked us to come over to the science wing of my high school. As I caught up with Alyssa, We started chatting and hypothesizing what this “experiment” would be. When we got to the room there were 12 of us. There were these pods and they asked us to lay down in these pods and they were going to scan our brains. They put us to sleep and then I when i woke up right away as If they couldn’t put me to sleep, but I was at my house now, in my own room but still in the pod. And everything looked different. Older. I went downstairs and I found my best friend outside playing with my nephew. I thought the nephew he was playing with was my nephew Andy who was 8. As I approach him to ask what happened to me. He sends Andy home and He starts crying and runs over and hugs me. I ask him what happened and he says that I have been asleep for three years. I realize everything that I missed, prom, college scholarships, first dates. I asked where my mom is and he says that she died two years ago. I asked where Alyssa was. He said that whatever they used to put me to sleep didn’t work on her, so she is now half way around the country in college. And then I woke up crying

So two days ago I had a dream about this one girl from my highschool, now i never seen her around, I didn't even know her name, but I added her randomly on Instagram(I was adding everyone that popped up), kinda forgot who she was and how she looked because she posts like 2 3 times a year.
So the dream goes like this: I was on the street that I have never been before (greenish background and it was late at night) heading back to this cheap motel that had neon red lights and I check my phone and I see I had a message in my voicemail. Now people in my country never use voicemail I don't know why and it's from her. It says that her date bailed out on her for the upcoming prom that is like in a couple of hours (I didn't know about the prom in the dream, but at the end of the upcoming year there will be a prom in real life) and she asks me if I'd like to go with her, without a second thought I call her and I only say yes and she is very happy. I head to the motel and there my aunt and my uncle have a room that is like their apartment combined with their old apartment (reddish background and lighting even though there is a little red in those rooms). My uncle somehow knows that I am going to this thing and has the jacket from a suit, a white shirt and a red tie, but no pants for this suit. Kinda looked cool and gives me these weird headphones (silver) like those you get from your phone but had some other features (never use them in the dream but I kept them around my neck). I go into the hallway and this girl is there is she hugs me for a solid 30 seconds really tight, and my aunt and cousin pass by at different times and they say 'no sex'.

Afterwards we leave for the party and I can only remember that the prom had this greenish background, I didn't see the girl around anymore, there were some things that happened at the prom but I can't remember anything. Woke up hugging a pillow(white, green and brown) and I felt like I had a crush on this girl but couldn't remember name or exact appearance but her hair and the shape of her face.

Yesterday, I went to drive ( I am in driving school) and I hoped I would see the girl in the city or on my way back, but no luck. I get home and I do some stuff for a couple of hours but late at night around 11 pm, I open Instagram and she posted a picture, it looks like the girl in my dream. Now you could say this was normal cause girls post pictures all the time, but it is the first time she posted a picture this year, last one being in Nov 2018.

When I go to sleep, I think about her and I want to see her again and it happens, I remember seeing her in my dream but can't recall anything in that dream. Woke up hugging the same pillow.
It is the pillow that I put my head on and before I never moved it around and I have 5 more pillows around me.

What does this mean? Should I try talking to her?

I'm 13 and a guy for context.
So apparently my mom had arranged for me to go to this weekend hangout thing for teens that ended on a Sunday night at a big prom. (something my mom would never do.) And Saturday was cool but I only remember a bus ride where the girl I was set to go to the prom with tried to talk to me but I was NOT having it I just wouldn't talk to her and she was a bit older than me like older enough to drive again weird. Well, the night of the prom comes around and we are apparently in a shared hotel room about to go. I'm laying flat on my back not wanting to go because dating and dancing are not my things. She says are you ready? I just remember talking to myself about not going. Then getting in her car to drive there. Next thing I know I get out of the car and just straight up walk back to the hotel. Lay down then go skateboarding home NOT supposed to be since I skipped the expensive teen event and left the girl, my mom, for some reason wanted me to hang out with. I also remember having wiped out on my board pretty bad but not injuring myself if that helps. I'm just curious since I've been having some girl trouble lately and wonder if this reflects anything about it. Thanks for getting this far to the few who did. Maybe you can figure it out...

So last night I had a dream I was speaking to a friend who passed away ( he was telling me that it’s true everything you do in this life will be accounted for in the next life ) anyway I’m in a hospital like setting with this lady with a note book , I also met a guy there he was a tall skinny fella basically telling me how my friends died , he explained to me that one of my friends death were instant then he explained to me that the other person they just took him because if he would of survived he would of basically been a paraplegic, anyway the lady was telling me it was my time to go soon and I’m like no way I don’t want to ,I asked her can I at least stay for my girls to watch them go to prom . I asked her for 10 years she rolled her eyes and told me no ! She told me she’ll give me 10 hours ! By this time I’m on the elevator leaving the building we were in . I scream to her give me 3 years at least give me 3 years she reluctantly agreed ! And then I woke up !
