Dream About Zombie Apocalypse Apartment Locking In With Soldiers

This dream was about

I had a dream I was in a small apartment like building with a friend and my grandma and these like soldiers came to let us know there was a zombie aapololypse happening and to lock ourselves in our apartment. I kept trying to lock the door but I couldn’t and one of the soldiers came back and scared me and said she look it for me, she told me we could go stay in a small part of the apartment and she could turn on this like two way mirror thing. This was just enough room for just two small beds and a chair! The zombies wouldnt see or hear us. We said yes. We stayed in the small part of the apartment and soon after the soldier left we staring hearing and then seeing the zombies coming. Apparently the part of the apartment we were in was made to look normal to the people outside that part but we could see everything. Zombies starting coming from everywhere, up stairs and everything. They were just filling up all around us, there was a timer that I guess was there to let us know when the protection of the area of space we were in would go dead or cut off. As my grandma and friend are sleeping in the beds I’m just up looking at all the zombies piling up in the apartment and what we’re going to do to get past them when the protection wears off. The clock is counting down and I realize it’s probably a dream so I start screammming my grandmas name to try to wake up or be loud enough for my grandma to hear to wake me. It eventually wakes me up before the zombies get in.
