Resistance Parking

Dream: The resistance was failing. People were being rounded up and used as slaves. I remember I was doing basic washing up in a small hut as the creatures were passing. "A" was chosen to be the one to stand against them, to voice concern, but we knew it wasn't going to work. We knew it was almost certainly suicide, and "A" knew it as well. But something had to be done.

Then we were driving. I remember thinking that a lot of trouble had been taken to ensure all of the cars were from the 1970s. I wonder why? The police gave chase, but all of their cars were yellow.

"S" was driving again. I didn't know she could. She decided to park in a stupid place that could only be reached with a good drive up and a jump across some buildings' rooftops. We landed badly, skidded towards a patch of water where the experiments were taking place. With a combination of the right minerals in a jar, and an electrical current, we could create a sentient creature, but the second one failed and it crumbled like a plaster ornament. 

Adventure: Another "post-apocalyptic" type dream, this time with some form of alien invasion. People being rounded up as slaves but the subject is drawn to doing the mundane tasks while others volunteer to do nearly suicidal missions. Is this their reluctance to get involved? Why were the cars from the 1970s? And what was this experiment to create sentient creatures? Was this some part of the resistance and would these creatures help to fight off the alien invaders?
