What are mansion dreams about?

Basically, I dreamt of standing on the lawn of my childhood home. Then, a woman I diddnt recognize (but looked similar to a college professor I had) said I could come in.

The house I grew up in, in real life, was firly small and only one floor. Though, when I went into it in this dream it had mutiple floors and was huge like a mansion. There where also green healthy houseplants all over, especially lining this really long and impressive staircase. I walked through all the rooms, noting how nice and big they all where (my old bedroom was longer and had a lot of nice furniture in it.)

Im a little confused as to what this dream means, as there are multiple interpretations online about the things I saw in it. If youre able to help, thanks so much in advance!

I had a dream I worked at a paint your own pottery studio and I hated it. The studio was in a large mall that seemed endless. The mall had ramps going every direction, wide walking paths, and I have no other way to describe this but when you're playing coin runners in Mario Kart in Lugis Mansion and the carts can just float down to the other floors. That's how this mall was. Doors and oddly shaped walls all over. The lighting felt like an arcade with the lights on.

I worked opening and closing. I was the only employee. The studio had only plain looking plates and bowls. The shelves with these plates went on so far I couldn’t see the end. The studio itself looked like an unfinished industrial basement.

My friends and family would come visit me, I would close the shop in the middle of the day, I’d let people use it for free. I never saw my boss once. But I couldn’t get fired. I woke up feeling shitty about a job I don’t even have.

Last night I had a mysterious dream that I still can't decipher the meaning of. It goes like this.
I am wandering around in a jungle and I come in front of a huge mansion with a huge door that is wide open. I enter through the door and find there are many rooms such that one room led to another through a back door. There wasn't a soul in that house, it was totally empty. Meanwhile it is dusk and the sunlight grew dimmer and dimmer as I began to explore the rooms. Suddenly I entered a room in which there were many gifts and presents scattered all around, half opened in their gift wrappers. At this point the sun had set and I heard that the main door slowly closed by itself.
I woke up at the middle of the night in a terrible fright.
Can someone explain what's the meaning of this deadly dream...

I was with a Beautyful girl i don’t know in real life, we had to go to a certain place for a job but once there we were informed that we had to wait til the next day
We notice an old mansion near and (thinking it was abandoned) we decide stay there for the night (i know it doesn’t make sense).
In the middle of the night we hear the noise of a door opening, suddenly we realize that this place isn’t abandoned and we hide in bedroom.
The owner of that place slowly enters the room , it appears to be an old and short lady that is talking to herself, she starts to tidy up the things in the room but suddenly she stops and says: “what did you just say? There are people hiding in my house?” It was only in that moment that we realized she was not talking to herself, she was talking to her husband but he was not a person, he was a tin cloud of smoke (maybe a ghost) that we had’t noticed before.
They start chasing us around the house and the entire place becomes bigger and shifts form, we even start hearing the voice of the husband that assures the lady that we will never leave that place.
For some reason i don’t really know (but in the dream i was pretty sure it would have worked) i stop in front of a tv and wait for the husband to chase me but at the very last second i move a step to the left and he ends locked inside the screen.
We find a door and leave, in front of the house we see an old car, we jump in and we run away (guess the keys were left inside the car)
We reach a party with lots of people and suddenly the girl i was with the entire time starts acting like she doesn’t know me anymore.
So i start getting confused and get away alone.
Then i woke up

I had the craziest most detailed dream ive ever had in my life last night. I’m new to Reddit but I honestly want some answers or some thing to why my dream was so weird and vivid. So my dream started off wholesome, I was dreaming that I was doing a smash tournament somewhere in California and I won it and drove back home in this car that wasn’t mine. I started loosely lucid dreaming and i started admiring the palm trees and other cars and I parked my car outside of this huge house like im talking a mansion and i just headed on in there like i owned the place and it was because I DID. i walked in there and i walked up to a room that had a a little gaming setup with three monitors and all that which is strange because I don’t have ANY of this stuff. but i just walked in there like it was just another day and i plopped into the seat and started scrolling through social media and i found myself on an app with a lot of celebrities and this is where my dream went south. at first i thought it was cool because it was a whole bunches of popular public faces interacting with each other with little comments and you could see their little icons but then as i scrolled i started encountering satanic rituals and as i kept scrolling i found myself looking at gore posted by celebrities. im not sure if i was lucid dreaming at this point but i started lookin for the snipping tool but i couldn’t find it but i did find a record button on the screen and i pressed on that and i started hearing footsteps in the house and then the footsteps multiplied so i rushed towards the door and peeked out the hallway and saw a couple dozen of men in black looking mother fuckers all the same height all the same clothes and all the same everything. i slammed the door and put a lock. i ran to the computer opened my Twitter and tried uploading the files there and at this point i was definitely lucid dreaming, i couldn’t believe how detailed my dream was but i was scared shitless. the bald motherfuckers were still knocking vigorously at my door while I was trying to figure out how to use dream Twitter and upload shit and when i figured it out it started uploading and the door swings open and i hear them story towards me i just cower under my desk and try and close my eyes but then i just get stuck on this darkness and then i slowly wake up to a tall skinny lanky creature with large cheek bones, a barely visible face, and long limbs and fingers and they take this headset looking thing off of my head and i look at myself and im a fucking baby, i could see my little stubby fingers and my baby fat on my thighs then i take another look around me and i see rows and rows and rows and rows of other babies in this headset thing with multiple long creatures monitoring them and i take a look back at the creature next to me and they started choking me. i woke up with teary eyes and my body shaking. i have been thinking about it all day and i have no real conclusion or closure on this. why did i have a dream so vivid, what did it mean, is it significant at all? thanks.
