A post-apocalyptic vacation

I'm at this resort-type town with my parents and sister - apparently spring break in some alternate reality. Like many trips with my parents I think was being driven kinda nuts by them so I often separated myself from the group. At one point I remember walking a long stretch of slippery sidewalk on my own from the beach to our rented bungalow (yes, a bungalow, I don't believe I've ever been in one before but there you go. In my dream it was mostly like a hotel room inside except from the outside it looked like a small house).

The next part was drastically different: I assume it was the same town but I got word that some catastrophe would take place, a chemical plant nearby was about to explode or something. Promptly I started gathering supplies and assembling a group with the people living around us to help protect from and perhaps even prevent the disaster. I remember tensions ran high as my family criticized me for being too detached from them and on my own as I tried to get everything together. For some reason, it seemed that fleeing from the town was the last option on my mind (probably because, like in many other of my dreams, that city became the world). At any rate, I believe it was here that my jaw clenched and as I tried to unclench it two of my front teeth came out. When I examined them in my hand I found something remarkable: they looked a lot whiter than my teeth had ever been; they had no roots but looked more like two pieces of white plastic, leading me to believe that they were not permanent teeth for some reason.

After a gap where I remember waking up for a moment, I came back to the same town but found myself on the street right after the disaster had happened. Giant piles of wreckage replaced where most of the houses in the neighborhood used to stand. People were left wandering the streets, most were looking for some provisions, methods of communication, transportation, etc. Right away I came into contact with the people I tried to galvanize in the second part of my dream. Most of them seemed disoriented and asked if we all could travel in a group. It was at this point that I realized that I was not standing alone in the first place, there were people with me who I really knew, some who are actually close to me in real, though they were not my family. I remember then that I went to what was left of my bungalow — the roof and top floor had been completely blown off — and took what I could use from it.

Later on I also found out that the chemical that had exploded would also turn my unknowning acquaintances into none other than flesh-eating zombies, though not me or my friends since we managed to find a shelter. I advise the group to rumage through debris to gather some weapons for general defense from looters and any other people who might have become crazed by the disaster. My reason was only partly true since in reality I wanted to give us, my close friends and I, an inconspicuous opportunity to gather weapons to defend ourselves against the rest of the group, if and when they ever turn. Garden equipment and some pellet guns were all we could find. We kept on travelling until one of the affected started to convulse a bit. Not knowing if they were about to turn or not, I had the pellet gun hidden out of sight but poised and ready. When it turned out to be a false alarm, I breathed a sigh of relief. "Here, you better have this; you'll probably need it more than I do," I said to the person, trading my pellet gun for that person's shovel. I then walked away from the group with my friends with the purpose of leaving town as soon as possible.
