Writing down a dream before I lose it

I was on the computer, talking to this girl I've known but never met. She says she has to go out. It just so happens, I am walking the dog. A car from the houses in the circle pulls out and I see a girl in the passengers seat with a guy driving and another in back. Two brothers and the girl I knew?

I follow (apparently forgetting about the dog)and arrive at hvcc campus apparently.

I pass a trailer for sale, not thinking much about it, and go into a large room, where maybe a handful of people are there including Steph,Josh, Dani, and the two I know online. They are looking at something and before I have a chance a bright green light fills the room. I drop to the floor shielding my eyes. When I get up, half of them are frozen in place. I scramble to the door with a few others who were not affected by the light, and see that the old world is gone, and winter has begun.

"We have to keep them warm." I said meaning those who were frozen
"We can't. The Arabs will gauge us for oil now. We will never make it through the winter."

I look back over and see Josh had left. I sighed. If anyone could of found a solution at that point in time, he could.

"They won't. Shut the door."

I walked over to one, a girl. It was either Stephanie or Ashley, another girl I knew online.

Suddenly she moved. They all moved. They didn't know what happened. I told her that people thought they were dead. It seems the only one who knew what happened was the first girl I knew online. I looked at her, but she wouldn't acknowledge my presence. She called for Ashley and they left together. Stephanie said she had to get to her parents and dashed off as well. I started walking back the way I came, and noticed this r/v or trailer. Apparently Josh was selling it, even though it didn't have his name on it. "$888.88? It's gotta belong to Josh." I called the number and said I had some of the money now and can give it to him. I settled into a little thing, driving down the highway into unknown.I was alone in the dark. That was the only thing I noticed. The dark and the cold.
