What are nuclear bomb dreams about?

So the first thing I can remember in this dream is being on a highway and missiles raining down on what I assume to be my home city, and at first I was a little anxious in a fight or flight kind of way, and then I saw a bus sitting on the highway abandoned with the key still in the ignition. I went into the bus and peered out the window watching the city go up in balls of flame and explosions. I was in awe and elated to see such magnificent destruction and raw power, but I kind of snapped out of it and went to the driver's seat and drove for a while until I was in an empty street with a dark green dilapidated house on the corner. I looked into the sky and saw three suns, a big one in front of me, and two on either side of me. I was amazed but a little concerned because I started to rationalize what I was seeing and thinking of what these suns could possibly be and for some reason I thought that maybe they were the aftereffects of nukes on our atmosphere. I ran into the house and on the TV a newswoman was talking about how the internet was down and their station was trying to get to the bottom of what was happening so: "people can get back to chatting on the internet" pretty wild dream, but I'm guessing the significance of the bombings was that I'm pretty interested in geopolitics and North Korea in particular. I can't place what the significance of the three suns could be though.

I had this dream last night, I was in San Francisco and I knew there was a bomb dropped in the city, I was far but not far from the radiation, but instead of that there was snow... And when I look away and look back I saw a totem pole and a Buddhist prayer flagpole, I was confused and there was a Christmas tree's a lined up in my front yard and it had lights and everything on it, And I don't live in San Francisco? What does it mean?

The other night I had a dream I was at a dinner party at my brothers house. I live in Alaska and it was winter in my dream. Out of nowhere I ended up figuring out I could fly. At first I couldn’t control it and I was getting stuck to the ceiling. But when I managed to control it I went outside and I could fly as high or far as I wanted. And I could see all the landscape of my hometown. Then I decided to fly to Mexico. I remember so vividly flying over the boarder and going into Mexico which I’ve never been in my life. Any way when I get there there was this Mexican kid with braces and curly hair (and he was deaf) who I’ve never seen before and everyone in the town called him the Prophet. In my dream he waved me down and I flew to him to see what was up and he had this mural on a wall inside of a church. On the painting it showed the tree where eve had taken the apple of wisdom. And to the left of that was a painting of me flying titled “the miracle”. To the left of that was a painting of a 3 headed lamb with 3 eyes on each head but one of the heads had a stab wound. It was titled “the lamb (the sacrifice)”. To the left of that was a painting of 3 men in suits. Two of the men had white suits with eyes of every color all over the suits and they had no faces. The man in the middle was a blonde man with slicked back hair. This was called “the false prophets”. The last painting to the left was of 9 lights or shields flying in the sky. This painting was called “the revelation”. After this deaf kid showed me all this he violently started painting the tree from Eden and turned it into a mushroom cloud. Like a nuke went off. And he explained that the right side of the painting would be done after God unleashed his wrath. And after this there was some dialogue I can’t remember but then I flew up i into the sky and met 9 flying saucers that turned into metallic angels with golden wings. That was when I woke up. I read revelations growing up in a religious house but I’ve never been religious personally. But this dream I had felt like I was in revelations.

Recently over the past couple months, I've had a dream when I guess the sun(maybe moon) kind of explodes? I've had this dream atleast 3 times, it's always the same type of story? It's starts out either me knowing what's going to happen and trying to tell others or i know what's about to happen and I watch.
Dream 3:
I find out a volcano is about to erupt, I panic trying to convince everyone to leave but everyone says "there's no time" some girl after that had a brain injury and some helicopter came down and only took her. It obviously angered me but then I got distracted by a large boom sound (the volcano has erupted as I'm assuming). We all hid in a hospital,then I wake up in a home, it's night and I can see the volcano has started to erupt. I see the sun(maybe moon but the sky was gray full of ash) and it moves near my home and it was preparing to explode, it make like a black hole with white things circling it. After that the black hole thing moved away from the white lines, and then lowers itself and explodes like a nuke or a bomb,but it didn't affect me. It just scared me to the point I was trying to escape from something, someone,maybe nothing even. After that a giant futuristic robot was taking people who survived and after that kinda of a blur. A part of me feels like the girl is imposter in some way.
(Sorry for that bad english)

Hi, I’ve never really felt this taken back and shook/disturbed by a dream. It wasn’t necessarily nightmare but I can’t remember everything. I’m 22(M), engaged to my fiancé with a beautiful baby boy and our dog. I am your average midwestern person. As well, a believer of God and Jesus, but not a seriously religious individual. I fell asleep around 1:20AM and just woke up at 2:15AM. So I would assume I was in REM sleep.

So the dream goes like this:
There was something very eerie about the day it was taking place. Things weren’t right, the news and radio that was on were reporting of mass panic. I was in a weird house(not one I recognized). It was myself, my fiancé, our baby, our dog, her parents and brothers, and my mom, grandpa, uncle, aunt and cousin. Everyone was very concerned about what was going to happen. The only thing was nobody knew what was going to happen. Just this big event. I started packing my bags. A couple changes of clothes, my hiking/camping gear, my camera gear, food, etc. I seemed to be packing a bug out bag. As I am packing it, my fiancé yells at me to stop panicking and stressing because it’s making things worse. The baby starts crying and I just leave my bag and go look out the window and it’s storming still. However the door, window, and corner wall of this house had now gone missing. So I go and sit down, then the dog starts freaking out and shortly after everyone notices it. There was this white noise that was almost like a high pitch frequency that set the dog off first then people could hear it. It got more intense quickly. I immediately felt the urge to move quickly to hold my fiancé and baby tight. As I do this I felt a warm sensation as I held my fiancé, then bam I wake up.

I am not sure what any of this means. I’m now up almost an hour later, very taken back by this dream. Was it the rapture, a mass extinction event, a nuclear bomb? Regardless this dream felt extremely real. I’ve been researching bug out plans and things like that.

What does this all mean?
What would be the best resolutions to calm my nerves.
