Dream interpretation on my dream?

So my dream is a little odd, I’m not sure I believe dreams mean anything but I thought I’d give it a try.

kind of a stupid one

The dream starts as I wake up one morning, I go through my usual routine, wile on route to work(about half way) I finally realize that I haven’t seen anyone(at all), no cars, no bikes, no one walking, It’s a little weird but I continue on to work. At work it’s the same no one around…
It’s starting to get dark out, so I decide to leave work and go somewhere, on the way out I start to find things that was not there when I came in, a baseball bat on a desk (odd spot for a bat) so I take it, a large knife sticking out of a wall (…) take that too, as I’m walking down the hallway the ground shutters a few times (earthquake?), I get to the receptionists desk and find a handgun on the counter.as I’m putting that away I notice it’s starting to rain and lightning out(no thunder), (as I’m walking to my car I notice I’m not getting wet)as I get in my car the ground starts to rumble(thunder?) and I start driving, I stop at a red light, the pole is shaking violently when the first eruption happens, A great column of fire and smoke explode through the center of the street (to my right) and bodies start to rain down on and around my car, one lands on the hood and looks inside at me(they are bald, gray bumpy skin, glowing red eyes, mouths full of razor sharp teeth) I take off in my car dodging the new columns exploding all around me, as soon as they land they start attacking things around them(even each other) I won’t go into detail on what they do to each other, it’s pretty sick and as far as I can tell they are not that fast, and they squish easily../// now I’ll stop here, it gets pretty sick from this point on, but basically the rest of the dream is me fighting them off with the weapons I found until they kill me and I wake up.
What could that mean?
