I've had the greatly expanded house dream several times. Sometimes it's a house I rented while earning my master's degree - except I don't have a master's degree (despite dreaming about getting one every now and then).
I've done the labyrinth mall pretty often too - just a week or so ago, in fact. I'm retired and have dreamed of having to go back to work and it is also a labyrinth - and sometimes is also located in a mall which never made sense to me. Even when it's the usual building, the elevators can't be trusted. Sometimes I am pretty sure they go sideways. I've always put them down to stress and generally feeling like things were out of my control. It's interesting to learn that it's so common.
One year I had a recurring dream of going to a baseball game and catching a home run or foul ball, only to realize on closer inspection that it wasn't a ball at all but a grapefruit or a rolled up cutoff from someone making blue jean shorts or something equally silly. I had it several times. That summer, I went to a ball game and caught a foul ball. I've never had that dream since. That one remains a "hmm" thing for me.
I have also woken myself up by laughing aloud at how ridiculous whatever that last dream was. I have a lot of completely nonsensical dreams. I don't often remember the details but sometimes I do.
Edited to add: I went to the Reddit. My malls are just regular malls, not places where people live or attached to airports or anything. But they are stupidly big and difficult to navigate. But some people posted pics of a giant bathroom where the toilets are just all over and out in the open. Yep. I know that place. Except mine are always flooded. There was a pic like that too except the lighting was blood red where mine have normal lighting. To be fair, when I wake from that one I typically have an urgent need to go to the bathroom.
