Another one

Here's another weird dream that I've been having:

Dream #4
I'm in a town. The town appears deserted. A group of people and I wander from shop to shop only to find the shops deserted. Then it happens - a plume of smoke overhead. Somewhere on the other side of town, a shop disappears in a plume of smoke. We (the people with me) rush out to the streets and take shelter in a nearby shop. Just then, the shop we were in goes up in a plume of smoke and debris. It's then that we learn that the town rebuilds itself by destroying its old, useless structures.

What does this dream mean?

It concerns me that this dream (and the ones mentioned in an earlier post) occur on an almost nightly basis, meaning, they seem to repeat themselves as if they're part of a bad Astro re-run. It makes me almost afraid to go to sleep since I know what's waiting for me in dreamworld.

In these dreams, I can't change the outcome and my movements seem to be restrained. Can anyone help me decipher these dreams? Or maybe an escape from them? I hate dying in my own dreams.
