I'll share one that I recognized during the later stages of therapy last year.
I'm in a shopping mall. I know exactly which mall it is, it's actually one within driving distance of me in the real world. In particular, I'm at or near the food court, and the area near the windows of the food court has this large carousel.
All of a sudden, a passenger plane crashes into the mall. It's at an angle where the front half of the plane is embedded, mostly intact, right where the carousel used to be. It's on fire as well. And... the others at the food court barely react. Heck, most of them are filming it or snapping pictures to share with their friends. It gets to the point where I have to shout at them to call emergency services - and I also wind up telling at least a couple of them to contact news stations. I don't remember why.
Whatever it is, I can't wait that long. Fire extinguishers are easy to find. But near that plane, I'm going to need gloves. Unfortunately, the few people with suitable gloves nearby aren't even paying any attention. I basically have to BRIBE them with cash to get the gloves.
I get up to the plane, can get one of the windows open. Can't get the door open from the outside. At least a few passengers inside are conscious and one of them's able to hand me a crowbar through the window. I get to work prying open the door, manage to dislodge it... from there I don't fully remember how the dream goes. I THINK I might have been treating some of them for injuries (I DO NOT have paramedic skills in reality) but what I can say for sure is... at no point, ever, does help arrive. At no point does anyone else ever step up. ALL of the onus is on me.
It's worth noting that I'm unhurt by the heat of the plane. This is nowhere near as positive as it sounds.
Unfortunately, when I DO dream (which seems to be relatively rare, that or I'm so fatigued I couldn't recognize it), it's pretty much always gun fights or ambushes or terror attacks. Anything where people suffer AROUND me whereas I'm untouched, and it is ALWAYS stressful and NEVER feels positive. I don't remember the last time I had a positive dream that wasn't merely one of my deliberate before-bed "mental exercises" (I generally don't dream after one of those and they aren't exactly that positive or a healthy thing either).
