What are exit dreams about?

I am a 42 year old male, I've had this dream at least once a week since the age of 4 or 5. Sometimes multiple times a week, sometimes more than once a night.

It's always the same. I am being chased by a small blonde female child around 10 years old. We are running at nearly the same speed, she can't catch me but I can't escape. Sometimes she's older somewhere in her teenage years, never an adult, but she carries a large battle axe over her shoulder in a ready to strike stance. I know her intention is to kill me if she catches me. I know this to my core.

The worst part is the location, I'm always running on a very narrow stone walkway around the perimeter of a gigantic dome with a bottomless pit in the center and no doors or ways to exit the dome except to jump into the abyss below. So I have no choice but to continue running until I run out of breath and I'm physically unable to continue. I have yet to escape the girl and she hasn't caught me. Every single time I wake up right before she does.

Even though I'm an adult, I am still terrified of this child in my dream. The only deviation it's ever had is a few times a bush will appear on the walkway and I duck down behind the bush as if I can hide even though she's right behind me but of course she isn't fooled and begins to swing the axe and I wake up.

It's been 3 or 4 months since the last time I've had the dream and as crazy as it may sound. I almost miss having it, it's like a part of me has disappeared. I've never really considered a meaning for this dream until I no longer had it. I've had no major life changes to warrant the changing pattern. Not that I know of anyway.

Any thoughts

I was in this big pool underwater and I couldn’t get to the top, my dad was just at the surface watching me, and i could see him yelling at me, and i kept getting pulled down deeper, but sometimes my arms made it out the water, but everyone in the pool area was just watching me and yelling at me to sink deeper, so i let go and sank to the bottom, but the water ended and i fell through it like, looking up it was the bottom of the pool water and i was then falling through air. I landed in a pile of beetles that all had faces of people and they were trying to bite me, but i started squishing them and everytime I did I grew a little bit taller and eventually i was so big that i like filled out this box and i was then laying in a box with no exit, and i started kicking the walls hoping they would break but it was obsidian so it was too strong. Then i woke up

A LONG read....
A little background to hopefully give perspective...
Me, (38M) married, no children despite wanting to have some. Wife (35F) is incapable, something unknown at time of marriage. SIL (26F) moved in 3 months ago with her daughter, which I have been stand in father for. These last three months have been the happiest of my life, as I finally get to be a father in some sense, and I'm really good at it.
For reasons beyond my control, I've developed romantic feelings for SIL and on Saturday night at a group outing, we had too much to drink and told her. 🤦‍♂️ She told me that she doesn't feel the same way, but is attracted to me physically, but we agreed that nothing is going to come of it, and to bury it. Yesterday was the most anxious and guilt ridden day of my life, I couldn't keep anything down all day and after many awkward exchanges with SIL, I went to sleep.

THE DREAM....

I was in a house, I didn't recognize it, but when I turned on the lights, they would flicker and go in and out. My dad who is a master electrician appeared and told me that we needed to get into the attic and have a look, so we did. When I was I'm the attic, dad began to point out that all the wiring was cut and damaged.
When I said that I could start trying to splice them back together my Grandfather, who passed away in 2004 appeared at the bottom of the attic stairs and told me that it wouldn't work, and that I had to rewire my house. My Dad agreed and I sat there looking around, then a door appeared that exited up through the roof. It had no handle, only a deadbolt style lock. When I asked where it went, my grandfather said it was the reset door and that only I could open it.
My Dad warned me that of I did, everything below would pass through it, but not everything would come out on the other side.
A small stairway appeared leading to the door and when to it, when I touched the door, I heard it unlock and I passed through it.
Everything went bright white and I was in a park that is near my childhood home. I was sitting on a bench and there were people enjoying the day. A man I didn't recognize walked up and sat next to me on the bench. He asked me to look over towards the playground and I saw a seemingly more mature, yet far healthier and younger looking version of myself playing with three children. Two boys and a little girl. All <10 years old. I asked the man on the bench who it was and he said it was me, but happy. I asked him how long it was going to be for me to become him and the man told me that I'll never be him. That my chance for that life has passed and that where I am is where I will always be. I woke up and now I can't get the sound of the man's voice or his words out of my head.

I'm suffering a lot with all of this, and I have nobody that I can confide in with this in RL that won't pass judgement.

In my dream, one of my old friends had an apocalypse bunker and he invited me there. While I was inside of the bunker the apocalypse happened. Or at least he told me it happened. I started to live in the bunker with 4 people and we were trying to get along while the friend who brought us there kept going in and out constantly, saying he needs to collect food for us, but he never let us go. One day I found an emergency exit that opens the gate and finally decided to go out for myself. When I turned the door knob, all the lights inside of the bunker started to turn on and off, then I woke up. Do you guys think this dream has any meaning?

I woke up in a big grassy field in bright daylight with a giant tent on it (so big it has multiple floors/rooms). The tent was partially transparent and of bright green color.

I was holding a drink. Suddenly, it starts to rain freaking hard. So hard that the whole place, regardless of how open it was, starts to fill with water. People ran and immediately went into the "apparttents" (pun intented (pun intended))

I ran into the tent as well, but could barely make it into the hallway (there was a big tent underneath that was housed under the apartments). The water got above the tent level and the pressure of the water caused the tent to collapse a bit with me caught in the hallway. I was now underwater and stuck inside the tent, and couldn't breathe anymore.

I tried to push myself out but it was impossible, the plastic sides are now pushed so hard against me there was no way to crawl out. The water slipped away quickly, and I got out.

I walked around the tent and saw how multiple people or families were in each of the apartments.

One girl walked out. She wore a black leather coat with black pants, had a katana on her back and a black bandana around her black hair. Basically, everything about her was black.

"You're the new guy?" She asked. "Uhm, I think so," I replied. "What is this place?"
"We consider it Hel," she replied. "Random people go in but they never get out, and bad things happen every day".

"Nonsense!" I said. "This is just a dream I can get out anytime!".
The girl sighs. "Please don't, we already tried everything."

I ignored her and imagined a portal in the grass - a large stone frame appears with a hole inside, with a sign on top of it saying: "Exit".

"See?", I say with a proud smirk on my face. "Now we just have to walk inside".
"Well try it then," the girl says with a smirk on her face as well.

As I walk inside, I notice that I simply walk through the frame, ending up at the other side, while still in that world, rather than waking up.

The girl catches up: "Nothing works, it's not a dream. It's not going to do anything".

I got more annoyed now: "The fact that I can place this door makes it a dream lol, let me try one more thing..." while I focus on opening my real eyes. This time again, proving futile.

"Fuck!" I said. "Ok maybe this is something different, what do I do now?"

The girl replies: "You just have to stay and make the best of it, but really, it's not worth it. I tell you what, we organize fights until death. How about we fight and I kill you, at least you are out of your misery then..."

"But what if I win?" I ask. "You won't, you just got here 1 day. I'm heavily trained compared to you".

"Ok... if that's what we have to do.."

The next day I walk in the cage which is where the fight takes place. It's a big cage made of a leather lattice that allows the audience to look through but without being at risk.

The audience starts to fill: Humans and other creatures such as anthropomorphic crocodiles sit down and my opponent comes in.

When the fight starts, she starts to make a helicopter movement with her katana, flies up, above me, and shoots down with the point of her katana pointed to the floor, straight through my head. The last I can remember/feel is the point hitting my skull as I heard the sound of "a katana piercing a skull". Everything became black after that. And it remained black for a while until I woke up.
