awesome post-apocalyptic dream

OK so in this dream, I was some kind of Russian princess or noble, but my family left back home many years ago while I was left behind somewhere in South America I think. It was also a world where Russia actually modernized into a normal nice country. Also after my family left, nuclear war broke out and Russia came out unscathed while the Americas were decimated. ALSO our family kept magic fairy thingies which we could use to essentially store and retrieve our own memories, but to retrieve a memory was to break a piece of that fairy's body ://
Anyway, I was living in a town w my friends (including some discord server members). The town was more or less well off but resources were running low, and some kind of paramilitary order started taking over and fencing off the community. Also they took over food rationing and started allocating resources to us. Basically the organization wanted to use our population as some sort of army reserves, and anybody who left the city's borders even temporarily would lose access to rations for some time. Obviously, there were the fences to deal with, and giant mutated beasts roaming around buffer zones around the town to make it Even Harder to get out. This organization regularly kidnapped people from town and forcibly conscripted them too. It was fcked up and people complained they couldn't even go to the store because the stores were beyond the fenced-off borders.
I decided I had enough and would escape to my family in Russia but it would be a loooong journey. First I had to jump across the fences and run away from mutated beasts (who somehow could not make it beyond even the shortest fences). Fortunately, I myself was also mutated in the war, and gained the ability to jump slightly higher than normal and land gracefully down. Also I had my fairy thingy to give me guidance and act as a friend on my journey. It was rlly sweet because I yearned so hard to reach my family and let them know I'm safe ;-; but my fairy was there to encourage and talk to me. My jumping power also could be advanced as I used it more often, giving me the power to jump higher and higher. But yeah, I escaped the confines of our doomed town; there was a military patrol on the town's outskirts who saw me and was like "that's one of the residents. fine, no chicken rations for you lol" and then I was gone.
Of course, I kept going east but all the communities I traveled through were similarly taken over by the same paramilitary order, so I had to constantly hide from (or just ignore?) their agents as I went. There were communities of hostile giants too who just killed humans straight up. Eventually I arrived at some sort of giant retrofuturistic facility with a MASSIVE tunnel that was sealed off at the middle. There was no way to get through the gate without completing some kind of advanced chemistry puzzle, and because this was a straight tunnel with nothing to hide me, I would be vulnerable to any personnel or guards passing by. Against my best judgement, I went to the gate and jumped high up to the locking mechanism (it was a big tunnel ok). I didn't actually encounter any chemistry puzzle myself since it was like an internal gameplay check lol, so I just had to repeatedly press the button until I could enter. Every time I failed, the alarm would be raised but I could just press another button to turn it off lmao, but after a few tries I actually succeeded and could pass onward into the tunnel. Now this was a Big Ass facility, and it felt really open but also really claustrophobic. Beyond this initial tunnel, there were branch off tunnels and rooms, and I actually asked my fairy how fckin big this place was. Eventually I ran into some hostile agents that chased me, including one REALLY creepy one who kept teleporting short distances after me. I broke out of some kind of wall and fell into the ocean.
Apparently, the point where I fell out was the shore of east Patagonia, so now I just had to make it across the ocean northeast into Europe. Other European countries might have been overrun as well but I wasn't too sure what I'd expect there, but thankfully I was on my way back to my family in Russia. I was really worried that I would either not make it to my family, or that the journey would change me into something I wouldn't be able to heal back from even if I made it ;--; I actually cried, but my fairy reassured me and made me promise that if the worst came to worst, I would break off my memories of my past life to regain them and heal from whatever trauma I went through. It was actually really sad but also heartwarming ;---;
Anyway, the ocean was cold as fuk and I couldn't breathe underwater (though I could hold my breath slightly longer than a normal person). However due to my jumping powers, I could theoretically jump out of the ocean and out of the water over and over, and just get across by jumping. I tried this a couple times and it was actually beautiful to emerge from the water up into the night sky. But of course it quickly became obvious that I had a loooong journey ahead of me, and this type of travel wasn't sustainable. Fortunately, the ocean floor was actually inhabited by some kind of water giants who weren't as hostile as their land counterparts. I quickly ran to a group of water giant guards and negotiated access to a watertight facility beyond but they made me take out a loan to gain access. But yeah once inside I continued my travels safe from the water. Apparently, to continue traveling northeast I had to go through a series of puzzle/challenge rooms inside the facility as well.
The first (or second idk) challenge room was like one of those platforming video game rooms with a bunch of floating blocks moving through the air, that you had to jump/walk across to reach the other end. If I fell down I'd have to climb back up at the room's entrance and try again. Initially I thought this was easy, since there were far more blocks than necessary floating to make a path across, but there was a twist. The room's exit on the other end was guarded by some kind of chess-like army, and the other half of the chess set was located on one of the floating blocks in the middle of the room. So the actual challenge would be to play a chess-like game, except the pieces would also have to traverse the floating blocks. Ofc this would be much harder, but fortunately I had a group of people traveling with me now, including Shikamaru from Naruto lol. And this was a chess-like game but not exactly chess. But yeah we started playing to make our way across, and I woke up ;_;
