false awakening

Start off in a building running away from zombies, after running for a while, i get surrounded.
I escape through a narrow gap in the horde.
The keep scraping me with their hands and grabbing onto me, but i brush them off.
Suddenly i'm in the corner of a right-angle corridor, and 5 people are here. A fat zombie boss emerged, and there was one guy with loads of weapons.
He handed them out ot all of us, then i ran away.
I realise i'm not being chased and the other guys are nowhere to be found.
I slowly start walking back, and realised they all died.
*Dream Becomes Lucid*
I fire my gun at them, but only water tricles out, its a plain water gun.
As they are closing in all directions, I scream to wake up, but it comes out as a whisper, then i wake up.
*Throughout this there were false awakenings*
