What are safety dreams about?

I had a dream that I was with my boyfriend and a random female character from a show. We were adventure hiking in Madagascar -- seemed we were in the jungle. We came up a steep rock drop and they geared up with ropes and harnesses to lower themselves down it. I was excited, thinking we'd be rock climbing (I like climbing) but when I realized we were just navigating down, I ignored safety and kind of recklessly leapt my way down. I remember doing dangerous balancing acts and the like, thinking "is this a good idea? Am I going to die?".

Then we entered this ancient temple. It was kind of buried in sand, I think, but we found an entrance. Inside there was this cool library that struck me as abandoned. Weird it struck me as abandoned as overall we were in some lost-to-time ancient structure. I remember the other two were wandering the library and this one, out of place book on a pedestal caught my eye. It looked pretty new age and I debated going up to it but instead looked past the library to find the inside of the structure. There were beautiful green, greek-style pillars and it seemed a massive room that went a long way down. I tried to draw the others attention to it, like, "screw the library!". The random woman character at that point was sat on a couch glued to her phone. I remember kind of losing it on her. "Do you see this shit?! This is no time to be absorbed in your stupid phone. There's a whole life to live out here!". Anyway, my boyfriend and I ended up leaving her there and continued on.

As we were exiting the temple out the other side, I presume, there was a desert scene. We came upon some fellow adventure hikers that looked marine-ish. We were all geared up, heavy packs and the like. I don't remember being perturbed by the rough conditions -- I like for things to be difficult. Once in the desert thought I could see, way up on this impossible looking kind of hill in the distance, that there was this huge madagascar-like tree that I was under the impression we were heading towards. Its roots were visible to me somehow, through this narrow kind of hill it stood atop of.

While in the desert we came across the marine-ish characters camping in the distance. They said something like, "this is what it's about. Watching you kids become good at hiking.".

We continued on until we came upon a glacial river. The landscape obviously changed accordingly. At this point I recalled, as my boyfriend tried to show me how to navigate over this thin ice without breaking it, that I'd had this dream before. The last time, I broke the ice and he got mad at me. This time, I guess I succeeded: I got over the thin ice and delved into icy water, but was blown downstream by the current. He had to come after me and catch me with his hand. This is around where the dream ended.

This seems utterly fucking packed with significant symbolism. ?????? Ideas very welcomed.

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.

I am a male, 29, Hispanic/Caribbean/Polish hybrid, currently recovering from chronic depression. I am a carpenter and aspiring writer. Strongly considering reentering the dating scene, currently single of course.

Basic context: in my dream I am some kind of mercenary or special agent who works with a small group of others. My ability is that I can become incorporal like a ghost and possess the bodies of others. Just as often I find myself rewiring and doing work in my own body.

The environment is all metal, like some kind of high tech research station or even a space station, though I cannot recall a specific detail concerning that. I work with my real life brother, a friend, and an older, statuesque woman who wears glasses. Together we are doing something important.

The meat of the issue: at some point as we are working, we are tasked with recovering a person of interest who is at risk. Our enemy is undefined, and the dream consistently implies that our adversaries in general are not constant, depending largely on what we are doing.

We recover this person, a girl wearing a purple wig and wierd contact lenses who is some kind of online streamer. She has no idea what's going on but is relatively compliant when we go to get her, which is a good thing because our escape from her location is one of the very few moments in the dream where I can remember our team being shot at, and us having to just run for our lives.

We get away, have to keep her nearby until the job is done and the job continues. She can't really help us, but she's funny, a little weird, but charming. Eventually (long story short), we secure what we need to secure to end the job, and her safety is no longer at risk so we plan to take her back to where we found her soon.

We hit it off well in casual conversation and mutual interest, and so when we conclude that its safe to take her back, it occurs to me that I could ask her out. I decide to do so the next time I'm alone with her (my friends are great but theyr also assholes). I ask if she'd like to go out and see a movie or some such (I say it more awkwardly than I thought I would, even though I'm not really feeling anxiety) and she agrees.

I'm feeling alright, definitely up beat. I end up going to another room to work on a computer and tell.my friend who is there that I have a date after the job is done. He's happy, I'm happy, and then...

One of my fucking teeth becomes loose in my mouth. It feels really really real, and I reach in and touch it, finding it very loose in my gums. I push a little and it pops right out. Well fuck me, I have a gap tooth grin now. Definitely not something I'm trying to have with my first date in nearly a decade.

I try to put it back for a moment but stop a second later when I realise that isn't going to work, I need a dentist. My friend is basically in shock. Just as I'm going to leave to start doing something about this, I feel a pressure in my mouth and then a crack. SO REAL!!!!

I open my mouth and fund another, larger tooth has SHATTERED in my mouth, what the fuck?! I begin spitting tooth fragments out into my palms, but after a second I realize that the fragments are;

1. Too numerous.

2. Too thick

3. All blue and marbled like Turquise stone.

I open my mouth again and go to a mirror to look at the tooth and see that it, or at least what's left of it, is turquise, a cracked flattened bass of turquise stone. I keep spitting it out and even pull the rest of the base out of my mouth gingerly. My hands are almost FULL of broken shards of blue stone.

This makes me panic, and that panic wakes me up.

I would have dismissed this dream normally, but so much about it stuck with me and so much of it was SO vivid. I feel silly for asking honestly, but, does this mean something?

I had a dream where a nuclear apocalypse happened. The dream started in my house. I don’t remember the bomb actually going off, it started during the aftermath from what I remember. I remember that for some reason my house was a completely indestructible nuke bunker despite literally just being my house. I looked out the window into the neighborhood I have lived all my life except it was completely lifeless. There was also a blue-gray tiny to everything. I remember this making me feel incredibly sad. There was then a passage of time, I don’t know how else to describe it, nothing happened but I could tell that at least a day passed. After this “passage of time” I stepped outside, looking at my neighbors house. After a few seconds one of the family members ran out of the house, saw me, and started running towards me. I somehow knew she just wanted to come inside for safety but also for some reason I didn’t want her to? I don’t know. I quickly stepped inside and locked the door just in time to stop her. I can remember the panic in her voice pleading me to let her in. I didn’t. This is what I remember in detail. There was much much more to the dream but this is what I remember clearly, the rest is just jumbled bits and pieces that don’t make too much sense. Sorry if it’s hard to read.

I was running on train tracks and just managed to get to safety and not get hit by the train. I then saw five people lined up and get slammed by a train. It was very vivid and disturbing. Lots of gore. I also remember walking on a walkway that conforms to the curve a big bridge ( very high up) and being scared and almost falling.
