What are circle dreams about?

About 2 months ago I had a dream that I was still in high school (currently I’m 19 and not going to school). Now when I was in high school I was always that one weird edgy/insecure kid that sat in the back of classes always wearing a hoodie, listening to music, not having any friends and sleeping through my classes (still somehow passing, though). Towards the end of my senior year my dad got a new job and couldn’t pick me up from school as much and since I couldn’t afford a car I relied on my 2 friends and brother that all graduated a year before me.
In this dream when school ended around 3:15 I texted my rides asking if they could come get me (regretfully as I always felt like burden to them). When I got no response I decided I would just stay sitting out in front of the school since it was a nice day and eventually walk home if nothing else happens.
I guess there was some after school event because there was a lot of activity in the parking lot after the sunset and people were starting to leave from said after school event. As I sat there watching cars pass by me I became more and more depressed by the fact that none of them saw me or they just ignored me.
After the main crowed left there was one car that stopped and asked me if I needed a ride and coincidentally it was my high school crush at the time. I got in and told her my address, we talked for a bit until I started to drift in and out of sleeping (in my dream not irl) while the song “circles” by post Malone played on the radio and she gently hummed/sang to it.
At some point I leaned over and rested my head on her shoulder as I felt her hand slowly reach over and grab mine. I felt nothing but pure bliss in that moment. It was such a pleasant dream that It turned a song that I once hated in real life for being over played into a song that I now love and consider to be one of my favorites.
I’m sorry for the long read but I really need to share with someone that isn’t my girlfriend, I don’t want her to be upset that she wasn’t the girl I dreamed about. I hope my writing isn’t too bad I’ve never been one to tell stories.

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)

I just remembered last night I had a crazy dream and then woke up and couldn't move, so I started talking out loud about the dream cause I thought someone was around and someone kept talking back to me about it, I was like "that was a really cool dream honestly" then they'd be like "i bet, talk about everything coming full circle" and I was just like "right dude, nuts." Anyways this went on for what felt like 15min then I dozed off again. Im just remembering it now but holy wow, craziest sleep paralysis I ever had, my deamon low-key a g. But yea I live alone so it was weird.

This has never happened to me before and its kind of freaking me out. Im wondering if anyone else has experienced this before because nobody in my circles that I asked ever had.

This is the dream:

This was a few nights ago and im still fucked about it.

I was at my childhood home, my parents were really old and frail (75/80’s, they’re actually in their 40’s irl) I felt like i was 24/25 (Im 19). The tv was on and I was cleaning not paying attention when the tv had a really loud alarm. The news guy said that america has fallen and showed huge street fights with fire everywhere and people getting shot and falling by the hundreds. The same dude came back on with another alert and said that the outsider countries that were waiting to attack have just declared war too. The phone rang and I watched my younger brother (18) answer it and hang up. I couldn’t hear him or anything else. He didnt say anything but him and my other brother (17) went upstairs, got a bag and left the house. I knew they got drafted to fight and I knew they didnt say anything bc they weren’t going to come back. My dad got up and hobbled to the door and said he had to protect the family, but I knew he didn’t want to go. He was doing it out of duty, and everyone knew he was too old he would die for certain. My mom was crying and so was my little sister (9) and so was I. Then there was another emergency alarm on the tv to immediately get underground and put something between your teeth and bite down, North Korea was coming. I got my family to go the basement and I was coming behind them, still upstairs when I looked out the window and saw a blinding white light growing and I knew I was going to die right then and I had this huge feeling that I had let it get to that point. It was MY fault that it did.
The light became everything and then it became all dark and my eyes adjusted to see that I was in a moving hallway of sorts. It in space, made out of space, and I could see outside of the area but I was confined to the inside. It was like a black space snake and I was inside riding it like a train. Some of the space scales of the snake worked as doors and I could go into points of time in the future/past, of my life which was a tiny section of it overall and in general too. I looked inside one room but I didn’t go in. It was just trees in a swamp. I opened this other door that had a vibe™️ to it and instantly I was met with this warm yellow glowing light that filled the entire room (which had no walls, it was just the light) and it had the MOST loving feeling ever. It felt like the ultimate motherly warm love ever and I could just melt into it and be happy and safe forever and I was about to step in when the light shifted and formed the face of a lady. The lady opened her eyes and looked directly dead in my eyes and without opening her mouth or anything she said loud and clear: Speak. The sound was in my body and everywhere at the same time.

And then I woke up. And I remained fucked up because I’ve never died in a dream and continued dreaming ever before.

Also my interpretation of the dream was: i have to speak on what ive been meaning and KNOW i need to speak on in order to not let bad things happen. Im trying to write a book and Ive been too scared to start.

I was asleep in my dream (already weird i know) I don't remember being asleep I remember being woke up. By so something glass like sounding slowly tapping the window next to my bed. It's a big main window and I'm on the ground floor. I pulled the curtain and this scary as shit demon was just looking at me. More appropriate wording would be looking into me. Then he took his hand, which had these long black sharp onyx coloured looking nails that were slightly glowing red at the tips. Like they were hot. He his claw nail things against the window and using heat pushed them through the melting glass, then started making a circle. Like he was cutting a hole in the glass. I was fucking scared and as I flinched to turn and run it was like he saw sonething on the windowsill and just took off. I woke up in a bit of sweat. The messed up thing was that because I'm my dream I was woken up I thought I was awake. It was a weird sensation, like an actual memory where I experienced the fear.

I looked on the windowsill after I gathered my thoughts. I have this old book I found in a charity shop (I always buy random old books, I find them cheap and sort of collect them. I just seem to be drawn to them, I ha e books fro. 1850s, over 170 years old about random stuff but I got them for like 50pence at a boot sale or charity shop)

Anyway it's a book of ancient and secret symbols used throughout history. A lot of celtic patterns and other stuff. I hadnt really read it but just flicked through it while watching TV with my GF. So I flicked through the book, a page had been once folded at the corner. It wasn't folded now but the crease in the page was noticeable. It kind of makes the page open at that page when you open it. On the page was a magjc word puzzle thing that is in a grid like a small suduko with words spelled the same backwards, forwards, left, right.

It says in the book that it's had different uses over the years. Apparently the devil was confused by it and it was used like a symbol to protect from evil. Then some religion used it because the central word makes a cross. TENET the N is the center of the grid and tenet runs up and across through the n. They draw a cross, write tenet up and across then fill in the other words which are rotas and opera.

I'll show a pic in the comments if I can find a link to one now

It's maybe just coincidence, or maybe because if the page I had skimmed through it and it was in my subconscious or something. But I can honestly say I only had a quick flick through it looking at the images I don't remember seeing that symbol/grid and didn't really read into anything beforehand.

Anyway I have the word grid drawn on paper and taped to the wall facing that window. No joking. That's how much this dream affected me mentally. It felt so real.

I feel like this old book saved my ass in some way
