My dream - lost in airport department store

I have planned a trip, and I will have plenty of time to get to the airport. I am at the airport parking structure, and I have to go round and round up the ramp. We get to a spot where some of the cars ahead are going straight, but a couple of the cars are peeling off to the left, and I know that's the way I should go, too. I edge that way, have to avoid a pedestrian or two, and proceed.

As I go farther, I see that instead of finding parking spots, there are lots of shoppers there. I proceed, looking for a place to park, but now I'm the only car, and I'm driving in what looks like a huge department store, with wide ramps that will accommodate both the car and shoppers. I round a corner and choose to go right, down a wide ramp, but now I'm in with shoppers and counters and I can hardly proceed. I choose the leave the car there, and get out and try to find where I should go on foot, scouting ahead, and maybe I'll find someone to ask. I find a young woman, nice looking, dark haired, a little confused, so I ask her how I get to the airport parking lot, but she is just confused.

I move on. I ask someone else who can't help. Finally, I find a woman of a certain age, gray haired, well put together, a pro who knows this place. I tell her my problem, I need to find a parking space, by now I'm not even sure where I left the car, and I have tickets, but even though I left home with plenty of time, with all the delays time is getting short. I get down on my knees and blubber a bit, I'm going to miss my flight! She consoles me and says, it's only $500. I say, more like $5,000. But she is taking on this problem like the pro she is, she's been here a long time, knows every nook and cranny and every situation, and solving problems is her business. She leads me to another nearby department and put the problem to another older woman, also a pro at the store, someone who completely knows her way around. They converse, then I set off following my guide.

We come to a service elevator, or rather two service elevators side by side. We go to the one on the right side. Then the left side elevator comes and opens its door, and my guide keeps that door open and fiddles with some mechanical stuff on the side of the elevator closest to the right sided elevator. I step forward to the right sided elevator and I see that the door is open, but there is no elevator there, and I look down the shaft. It's a long way down.

I step back and think, this is getting dangerous. I'd better wake up. So I do.
