Just My Dream and Motivation

it wasn't a dream of fairytale.. i just want to share it with you guys because it's kind of disturbing for me.. the images were too vivid. could it be our future? maybe i'm just exaggerating but well, comments guys. tell me what you think about it.__.

'humanity was on the verge of collapsing 
barren lands 
hardly any water 
several of us (me and my friends) were survivors 
we survived through the hard terrain and wastelands, the rest of the world were zombified, feeding one another 
we somehow wound up into a running city 
humans, but they're inhuman 
we were sent for execution after we set foot in the city 
they blockaded our way in and out 
we were trapped like mice 
of course, i was so angry i asked them why the execution 
their snotty leader said, they can't be sure if we're infected or not and that's another mouth to feed for them and they said that they've trapped the underground subway full of zombies if we wanna get out 
it's impossible for any of them to venture down so we were sent there to our deaths if not the death by bullets 
well, i had to lead all of you guys down there but we're like a whole swarm of ants 
i couldn't be sure to handle a large group 
a really nice native came to us saying he was told to lead us down the tunnel 
he felt sorry for us and i see he tried to help us 
but he couldn't so we parted ways, he had to return and we have to venture down 
it was really dark and i can sense the dead roaming about 
but in the darkness i saw my other friend; it was T. 
he pointed a safe route for us and then disappeared 
i warned the others not to get separated and split the team into teams of capable fighter; me, R, D, E, J(?!), several others n the 'civilians'; i don't remember either 
we made our way into the darkness, i wasn't sure of T's direction n heading for an armory to the left (opposite of T's direction) 
we grabbed as many weapons as we could and head back to the 'civilians'; they were attacked we panicked, some were even bitten and i had to shoot them, 
another horde came and i don't remember the rest 
but i managed to survive just me, D, R, E and..J (in real life, J is an idiot; i don't think he would've made the capable fighters)-___- T was with the other FEVER members (FEVER is my band; there are 8 of us) 
the rest were dead 
I SWEAR J WAS SO RECKLESS I MIGHT HAVE SHOOT HIM IN THE HEAD THE MOMENT I GOT MYSELF A GUN 
he had this flashlight and swung it around like a toy when from afar there was a zombie wandering and if it notices us, we're doomed before any of us could get our hands to any weapons so i told R to muffled him (in the first place) 
it was a bloodbath n we were lucky T and the FEVER were already inside 
n good for them they found themselves a safe house 
i dunno if this dream is going to have continual 
maybe there is no way out from there' 

 scary? there're lots of things scarier than this but imagined; humanity collapsed, barren lands, scarce water. this is one of our many possible future if we don't do anything from now. people, let's save our planet! there is no place like home!
