Lucid Time!

I was exploring some kind of post apocalypse earth. I was in the desert, with someone else. (I can't remember who) They said we were walking to the "Grand City" that was apparently mankind's last stronghold on the planet or something.
The desert was hot and dry. The sun was low in the sky, and there was not a cloud to be seen.
We walked over a sand dune and saw a huge city. Most of the buildings were damaged but they looked like they were being repaired. I could see people in the streets. The person I was with pointed to a good-size building in the middle of the city. They said that was the capital building. But the most notable feature of the city was the huge river that ran through it.
We entered the city and went to the capital building. It was essentially one huge room with glass walls and concrete supports. Roughly a fifty-foot cube on edge. The ceiling was also concrete.
We entered and the first thing we saw was construction workers putting an additional support column because they thought building was going to fall. Then we came to the leader of the city.
He was some kind of king sitting in the middle of the room. Sprawled out on his throne holding a glass of whine. The dream character I was with and this king started talking. Without warning, the building buckled. I remember seeing people panicking, and debris falling from the ceiling. I started running, back out the door onto the front lawn of the structure.
I realized it wasn't the same building anymore, it was my house. When the earthquake stopped, i saw a fire start inside the house. I went back inside. My grandparents were in there. I asked my grandparents if anything exciting had happened. My grandparents just sort of rambled on pointlessly. Disapprovingly, I got the fire extinguisher and put out the fire.

I was making my way along some railroad tracks, no longer in a desert. I was with that other dream character again, but I cannot remember seeing them or anything, just that sort of feeling that a friend was with me. Until eventually I came to a vaguely familiar home made of pink stucco and orange ceramic tiles on it's roof.
The home seemed to be in a tropical setting, on a hill, surrounded by a couple of palm trees. There was a huge mountain behind it.
I went inside and someone was in there, I cannot remember but they seemed to be good friends with me and the other dream character. Got out my computer and tried to go on minecraft, but the computer had a fatal error.
I remembered the other DC telling me earlier that there had been some kind of Electromagnetic pulse. And apparently it had caused all of the computers on the planet to malfunction.
I can remember the inside of the house being dark. The person who lived there gave us cookies. Then she told me that If I wanted to leave, there was a creature I could mount in the pen outside her house.
I went out to the side of the house. There was a pen that matched the house, a high wall made of pink stucco. The top of the wall was also covered in orange ceramic shingles. There was a large animal that you could ride. I could best describe it as a llama or perhaps a really ugly horse.
There were a couple of stairs made of wood that you could climb to more easily mount it. I got on and started to ride around. The animal was very easy to control, even with no practice.
I started to leave, without the other mysterious DC and while I was walking, I took out a camera, and started making a video cast for the internet. I told people that there was an apocalypse and I was currently riding a llama.
