I vaguely remember telling Jonathan (from the same Mummy movie) that this was a spot where an ancient temple had been buried under the sand. Then I went up the sand embankment further back into the "yard" where there was a more levelled-off area.
This new area was almost like a second back yard, and I noticed bits of what seemed like another temple half-buried under the sand. At first, they were more the scale that would make sense for an actual temple, but as I started looking around, it was more like a huge model of a very large temple. I was able to remove some chunks of hardened sand that were almost like big, loose stones around one particular section of the model, and got the uneasy feeling that I wasn't actually sure how stable any of the ground here was, especially near the parts where the temple-model poked through the sand-ground.
I mentioned to Jonathan that the lower area of the back yard we'd already passed through had a temple buried under it, and that Indiana Jones had gone through it in a previous movie. (This is the first of several references to the dream actually being a movie of some sort, and yet it was also real-life, and I never seem to bridge the mental gap there.) I added something like, "You know, the one where he runs through going 'RAAAR RAAAR RAAAR!'" and Jonathan said something to the effect of, "Yes, and the Egyptian Government buried that temple on purpose."
I waved my hand like that wouldn't be an issue, and then said something like, "Oh, well I will have to poke around my contacts and see if I can do something about that."
By that point I seemed to have forgotten that the ground might be unstable, as I ended up sitting on the ground looking through that bit of temple model I'd uncovered better. There were miniature trucks and other more modern accouterments that definitely didn't fit for something untouched. Someone had been here recently and it almost looked like they were planing something, but what?
Then I found a miniature crate by one of the trucks, and looked through it. I said, "Come look at this, Indy." I don't remember Jonathan being around any more at this point, I think the dream forgot him, but hey, we traded for Indiana Jones, I guess? Anyways, I had picked up one of the small figures that was being stored in the crate; the figure being about as wide as a Lego minifig but about twice as tall, not blocky, but about the same amount of articulation.
The figure was me. I was dressed a bit like Princess Leia in a white pants suit kind of outfit, and from this point I think I was supposed to be a weird Leia ripoff character in the dream-movie. There was also a figure of Indiana Jones and a few other characters who were supposed to be in this movie, good guys and bad guys alike. I'm not 100% sure, but I think there was a Darth Vader in there as well.
Indy agreed the discovery was pretty spooky and this must be something the bad guys were using. Maybe we could find some kind of clue to what they were up to if we kept looking. He wasn't the only person around, but I don't remember who the other people were, aside from friends or allies. The next thing I remember is saying, "I found a new one of me, and it has batteries."
I was holding a figure of me that had the top half covered in plastic packaging, with a tab coming out of it like the sort that you pull out of an electronic item that has batteries, and the tab is keeping the batteries from connecting and wasting power until the thing has been bought. I took off the packaging and pulled the tab, and there was a tiny button on the back of the figure.
I pressed it, and the sound was so quiet with other people making noise around me that I had to hold the toy to my ear. It said a line of mine from the movie (that we were currently in, but I still wasn't connecting the dots completely). I kept pressing the button and listening, and it had a lot of my lines. Then I heard something that made me say, "That's not even from this movie, that's from like... an improv I was in."
I checked Indy's figure again and realized it did actually have a button. His lines were a lot longer, and I listened to a few of those. Then one played that wasn't familiar, and I realized it must not have happened yet.
The line was spoken in a tone that gave me the impression he was reluctantly working for the bad guys, but I figured he must just be pretending to do so. Part of it was him saying, "Yeah yeah, fly from [city name I've forgotten] to [other city name I've forgotten] on the top of an airplane," and I was starting to visualize what he was saying. The dream pulled me into the visual of him standing on top of a stunt plane flying through the air, and suddenly another plane flew past. I watched myself in a flaming stunt suit jump from the other plane onto Indy's.
The flames went out as I held onto his plane with him, and the plane was attempting to fly towards its destination which wasn't terribly far away, but the winds were high and impossibly-tall phone lines and hanging-bridge supports were making the path difficult.
Then I woke up.
