water dream + driving dream

I want to share these dreams here because I can’t make sense of them ~ the metaphorical meaning of my dreams is usually immediately and strongly clear to me, so I’m feeling a bit foggy about these ones.
 
We were at someone else’s house, evidently having broken in or gate-crashed the place ~ however we got in, we were not supposed to be there, or so we thought. We were having a party of sorts, being somewhat raucous, jumping in the pool, playing music, generally being a nuisance, like teenagers or something. There was a moment when I was underwater, though I couldn’t exactly see or feel the water ~ I just couldn’t breathe and was worried, and floating. Someone told me there was air over there, and I moved myself to where there was a straw-like thing coming out of a flat-ish round plate, and when I sucked on the straw I got some air, but it was kinda bubbly or fizzy (like I was sucking on a soda stream gas bottle) and wasn’t entirely satisfying, but it seemed to be enough, and that was the end of that scene. Later, the owners of the house came home and parked their cars behind ours, and we couldn’t get out. We panicked a bit because we would have to face them, but I resigned myself to it and when we interacted and we said sorry for being in their house, they said it was okay and they had been observing us from the neighbours’. The people I was with were indistinct, and they feel now like they were more like aspects of myself than like distinct entities.
 
In the other dream I was driving a late-model manual car (and I’m uncomfortable driving late-model cars in waking life as it is), but in this dream it was worse because I was sitting askew in the seat and having trouble both steering and changing gears, but this only become evident when I shifted position and suddenly I was driving like a normal person. I was still struggling somewhat to change gears smoothly, but I was making progress in learning how to drive this foreign vehicle, though I felt very much like a learner driver. (In waking life I’m a good driver, and can even drive semi-trailers.) At some point, my perspective shifted at the same time as the car careened out of control, left the road, and ended up in a grassy ditch. I watched this from the median strip and it felt distinctly as though someone else had been driving and was responsible for the crash.
 
Three events from waking life that may be significant: I had a friend over at the house where I’m house-sitting, and on her last night here we got boozey on the back porch ~ she’s an effervescent person and quite loud, and there was a moment or two in the early morning when I worried we were disturbing the neighbour; at the house where I’m house-sitting, I accidentally broke an incense holder that is shaped very much like the straw-thing I sucked on for oxygen; I was playing a racing-car video game recently (which I rarely do ~ and I rarely drive actual cars these days) and I totally sucked at it, crashing all the time.
 
I’m very much interested in the question of whether dreams are merely the brain integrating memory or whether they come from a deeper source, like the collective ancestral mythological memory. These two dreams I had, they happen to have elements that correspond with my waking life, but if it’s more than just memory integration, am I being told some message from my unconscious through the collective memory? Like, “Don’t be a douche by getting boozey and keeping the neighbours awake” 😀 Probably there’s more to it than that, so I invite and welcome any and all other interpretations.
