walking dead dream

I had a dream that was like the show walking dead.
it was back home where I grew up and where the school was in the back yard there was an underground world.. it was all demolished and homeless people lived there. I had to make friends with them tho to get to my home and I had to go through a door way but there wasn't a door
I know none of that makes sense
the dream was like a video game... and deep underground in this other world it was a dangerous place I had to make friends with these guys the homeless people... BUT they were not aloud to go through the door with me.
but they did cause they helped me
ok so now im in the back yard of my old home and now I meet up with this 7 foot fat ass lard who has a large knife and hes with this younger girl with long black hair who also has a knife
they both want to kill me and stop me from going back home
then out of the blue im with another girl who is like me has to reach my home she doesnt make it cause the knife girl got her
the big guy with the knife almost got me but I did them both in
I walk in through the door and everyone of my family is there
they look at me with shocking eyes cause im covered in blood. I told them what had happened I had to do it

then I woke up felt like crap!
I don't like that show the walking dead but I did catch a part while surfing through channels and caught this part https://undeadwalking.com/2016/03/12/the-walking-dead-did-the-group-go-too-far/
I seriously do not wanna go looking for the video for this
seeing that clip is prolly the reason why I had this dream.
