Dream About Running From A Zombie

I was running away from something I didn’t know what it was, I was too afraid to look backwards and find out. I was in this swamp area, as I was running I saw this nice house, but to get up to it I had to jump on these large rocks and keep my balance not to fall off and die. When I got up to the house, there was no door. I started to freak out inside, whatever was coming could get inside. I found a door and put it on the frame, except there was about 2inches of space between the door and the frame, it didn’t fit. I still deadbolted it. Then what was chasing me got to the door, it was a short slimy green looking zombie, it squeezed itself between the door and door frame and got inside. When it got inside it turned into a regular man, a woman from the kitchen ran to greet and hug this man. I was still freaked out, and scared for my life so I ran to the kitchen and grabbed a cast iron pan. The man was on his way out the back door, I hit him as hard as I could in the back of the head. I heard the woman Audibly gasp and was staring at me with wide eyes and a pale face. I just looked at her and said “what? he was freaking me the fuck out” then I woke up.
