The memories have somewhat faded from last night's dream, having had to get up q7uickly to get to an appointment and only just gotten back to a suitable keyboard, but there was more Geography[1] in the early parts.
By the end, though, there was an abandoned lorry (US: truck; and single body, not articulated/tractor-trailer combo[3]), of the enclosed type with a car loaded into it and
big clues that there was somebody in the boot(/trunk) of the car, and a danger of fire. Which happened 'coincidentally' after we[2]'d actually discovered this event. It became clear to me that this was an exercise of some sort, set up to not be dangerous. I had the impression that the guy trapped in the car trapped in the lorry container above the danger (and, now, actuality) of fire had triggered the event himself once we were there to help.
For whatever reason, my fellow 'rescuers' were dumbass slow and I was shouting myself horse trying to get them to bring fire extinguishers (some were quite close by, right next to the theatre stage... Which makes sense only in a context I can't entirely recall right now... but both a CO
2 and Water extinguisher were available) to deal with the fire. Not through fear for anyone's life or anything like that, but more like when you've been asking someone to pass the salt and they've continued to ignore you even while you become totally riled about it. "LOOK! PASS THE SALT! THE SALT!! THAT LITTLE THING IN FRONT OF YOU!!! ARE YOU EVEN LISTENING TO ME?!?!". Which isn't like me (at least outwardly), but happened anyway. (About the fire extinguishers, not salt.)
Somebody must have taken notice and I went to investigate the cab of the lorry, and found a 'clue'. A particular piece of vehicle registration form on the passenger seat of driver's cab. (I know it was a 'clue', because by now I knew this was either an exercise or something akin to a "murder mystery weekend" playlet, although exactly which I couldn't say.) The vehicle it described was neither the lorry nor the car we found within...
I was hypothesising it had something to do with the identity of the person doubly-trapped within the vehicles (and currently probably still bothered by fire, unless by now the others had managed to actually get off their collective arses and deal with that properly, round the back of the vehicle that I was now at the front of).
But then I woke up. Still none-the-wiser. And while I might re-use some visualisations, I don't tend to dream 'sequels', that I've noticed[5], so I doubt I'll get an answer to the mystery.
[1] A popular theme of mine, where I 'know' the area (sometimes based upon RL, but always 'known' by my dream-self) and I even have access to a map, but directions don't work right. In this case partly because those around me were determined not to take the turnings I insisted on, but also because of 'discrepancies'. Large areas of the map were matt-black (off-piste, though, as it were) and the location we were heading for was marked on the map as being off the road to the left, up a small stream, but there was apparently evidence that the location we were heading for was further along, right on a small lane and "ask again at the cottage". Also, later, the map was photographic, and the "huge black areas" were revealed to be bales of straw (those round 'roll' types) on fire, billowing black smoke to obscure those particular parts of the map, in real-time... Each bail was proper-sized, yet somehow individually the size of large towns elsewhere on the overhead view. Dream logic!
[2] Whatever group of people I was with at the time...
[3] Hmm, what's the US term for that? UK: "Artic(ulated Lorry)" being a Tractor-Trailor combo, Big Rig, '16 wheeler', possibly "Truck"[4]; but is "Wagon" the term for the one-chassis, non-unlinking type of
HGV? Sorry, I just become curious about that. I'm sure I've known.
[4] Although, along with the derivation of "Monster Truck", I know an ex-colleague of mine (Chuck, based in San Diego...) had one of those 'standard', yet not really suitable urban-driving, flatbed-pickups with
stock large tyres which you had to climb in, and we always talked about "Chuck's Truck". And I'm minded of U-Haul 'trucks' which are of the kind I'm wondering about. OTOH, "UPS Van". Van. Right, maybe that's what you'd be calling the unarticulated lorries, your side of the pond. Still, it's right what was said about separated by a common language...
[5] At least not night-to-night. Although sporadic sleep with half-dozey wakefulness in-between sometimes does this. Especially if I think, while awake, of what I'd just dreamt, if that turns doesn't turn into thoughts of "what if?", and then the next dreamlet is a re-run of some prior bit of dream, going down the alternate path...
