Dream About Zombies Standing Outside

I had a dream about... zombies? I actually don't know if they were zombies. They were pale figures that still resemble human and act like a zombie, they appear mindless, sleep deprived, but there was something sinister about them. They weren't aggressive, they didn't eat people immediately because they were quite slow. Although they were intimidating...they can laugh when they see you. The dream replayed twice, the first one was when there was this guy and he also appeared on the 2nd dream. There were also two cleaners, there were plenty of cleaners patrolling the area although those two were emphasized. The dream was set in a some sort of farm, I was quite disturbed when it resembled the farm of my grandparents on my mother's side. I think there were two houses there and they were a few distance apart. When the two cleaners (one is wearing green and the other was wearing white) enter a room where the guy was at, they asked if they could sleep in for the night that was when everything broke loose. Then the dream re-occured again. I was there now including my family, i was in the room where the guy lived and I told him about the 1st dream, i warned him not to let the two cleaners in. Then suddenly i had a romantic connection with this guy, were were cuddling, and I wanted him to live, and it wasn't possible. Hell broke loose again, it was a different scenario now, i was separated from my family and the guy went out and he never came back. A few more people has seek refuge in the small house where I was in, they were panicking, I saw two familiar faces, there was betrayal when the girl revealed that the boy tried to push her towards the zombies, he tried to apologize and the girl was in distress in which I comforted. That night we helped each other to guard the house, we locked the doors and windows and secured them with other items as well. We were alert and if the locks were loose we quickly close them again. Everything was fine... actually no, fear was still evident though we secure the doors and windows. I then slowly realized that one by one everyone slowly disappeared until I was the only one left. The window suddenly opened, good thing there were railings, although I saw a zombie standing outside, I didn't see its face but it laughed at me. I began to feel more scared than ever...and I think it likes it. The windows were closed again, I guarded alone...and then I woke up.
