What are adoption dreams about?

i had a dream that i adopted someone else's identity. i had different (not from my real life) friends and life that i knew well. it felt so real that when i woke up i was really confused.
is it possible that my subconscious mind created a completely new person that appeared in my dream or was i dreaming someone else's dream?

I had a strange dream I don’t really remember much first it was some eatery . I was with my brother and we were trying to get something to eat . Then suddenly it changed to me being with my friends and they were trying to show me a page from where they r ordering cute clothes but notifications pop up and looks like my bf’s friends are trying to hit on me . Then again the scene changes and it’s like medieval time kinds of and I’m with a bunch of people and two of them are adopting a teen girl so to make her their blood child they make a cut and mix blood . And like idk wat happened in next scene I see my left ear is cut and it’s bleeding .and I’m very angry and while walking away I say if it gets septic or etc I will come back and destroy the whole town for doing this to me ? What does it mean ?

I had a dream where I was sleeping on my bed, and a cat (apparently I had just adopted it) was bouncing around the bed not letting me sleep. I thought to myself, oh I shouldn't have adopted a cat I'm no good with animals and I was trying to put it to sleep. Then I was awake and I put her out of the house in the hopes that it'll go away. Few hours later I went to the window to check if it has run away, and saw that it was lying lifeless. It was a tiny black cat with a white face. I remember feeling horrible in the dream about this.

I have never had a pet and I don't have any feelings towards any animal and I am horrified at what my mind showed me!! The image of the poor cat is not leaving my mind! Does this mean something??

Please help me translate this dream, it’s the first time I have a dream like this. I woke up and couldn’t stop crying for 10 minutes.

TLDR; I find out me(20 yo female) my 16yo brother, my 19yo cousin were made in a lab by our parents. My 8 yo half sister (from my father) was not, she was actually born naturally. I then get to see my creation in a lab as myself now, and I see myself as a baby in the end.
-
In my dream I randomly ask my mom if we’re (me and my younger brother well him Nate) adopted and she giggles and hesitates but then casually says yes.
Nate (16yo) doesn’t seem so surprised since he found out from looking at papers (which actually happened irl he’s been looking around secretly at my moms documents to find out things about our parents divorce)
He told me about us being adopted but I didn’t pay much attention.
Anyways, we sit next to our mom (then in the dream she becomes that other person, younger and skinnier idk) and behaves a bit more easy going. She answers questions we have (I can’t recall them now)
I feel so sad finding this out and wish I never knew, Nate seems ok with it almost like it doesn’t affect him at all.

Now the weird part that freaked me out.
The moment I was born. Or to be exact “made”.
My parents are at a hospital and there’s an Indian doctor who i feel like I’ve known my whole life (but it’s actually a famous figure who I’ve never met and just recently got back to their contact not an actual doctor)
That doctor is working with my parents about having a baby.
Somehow I end up in a laboratory with my mum and my dad (I am the same age as I am now but I can’t see myself, I see from my eyes but im standing there with them),
They’re making me in lab, I was made in a lab, my mom was mostly doing the work side by side with my dad, and boom BABY ME I see myself as a baby being created with the hands of my parents and I burst into tears.
My dad holds baby me and says look what a beautiful baby, baby me points at my mom and says “mama” then points at my dad and says “dadda” and then point at myself(I can’t figure out if it points at herself or present me) and goes silent for a few seconds. Then says “(my actual name)” and from their reaction it seems like they knew it was gonna be my name before baby me said it. They’re proud of baby me and themselves for making me. I cry so hard and say out loud the last thing that matters
“When you die I have no one. Not a real brother not real parents not real cousins or grandparents im by myself”

My mom gets mad and says “see that’s all she cared about” my dad says “see but isn’t it comforting? You could do whatever you want, risk everything, truly live without worrying about the results”
I woke up crying so hard.

I know this dream means something because I have never felt so strongly about a dream. Please tell me how to get the meaning it’s so early and I can’t go back to sleeping

I'm running through a jungle with a brown snake wrapped around me, his head above my right shoulder. We are speaking, but this doesn't seem strange at all. We're laughing and joyful, having a complete blast. Although this first part of the dream is harder to remember, we're basically going through this jungle with the snake teaching me how to swap conciousnesses with different animals. This is to teach me the "lessons" and physical experiences of different creatures while allowing them to spend time as a human to better understand us as well.

We emerge from the jungle and find ourselves looking across a vast grassland. To our side, following along the treeline, is an elephant. This elephant is barely touching the ground with its tiptoes, flapping its big ears and traveling in strangely graceful, gliding hops. Sharing a conspiratorial glance, the snake and I take off toward the pachyderm. Throwing a startled glance over its shoulder, the elephant flees. We take off in hot pursuit!

We're led on a long merry chase, until we finally catch up to him in a dilapidated amusement park. The rides are covered in rust and overgrown with creepers. The elephant heads straight for a small, stagnant puddle in an area of broken concrete. To my amazement, he executes a graceful swan dive right into this shallow puddle and disappears. I run up to the edge of the puddle before hitting my belly and shimmying close enough to peer in. Under the shallow green water is a perfectly circular hole that leads down deep into darkness. As I press my face closer trying to get a look at what's in there, the large gray head of a seal pops out. His penetrating, inky eyes unnerve me, and I scramble back.

His head disappears back into the water just as I hear a creepy little girl giggle behind me. Turning around, I see a girl of about 6 in an old fashioned frilly dress cupping something in her hands. When I ask her what she's got, she opens her hands and holds them up to me, still giggling. In her palms is my friend, the brown snake. He's been chopped into little slices that look like sushi roll pieces. In the center of each piece, there is an eye staring up at me, moving around. I shove the girl away in horror and start screaming "What have you done?" I tell her we were going to bring him back to life after the body swap, but now we can't, she's ruined it. I keep insisting we (I'm not sure who I meant when I kept saying we ) were bringing him back to life and am very distraught. She regards me calmly before adopting the creepiest condescending smirk. She looks me right in the eyes and says, "That's not what you were doing at all, was it?"

I wake in a cold sweat. I mean, seriously, wtf!!! This has got to be the most bizarre dream I've ever had.
