Weird Apocalypse and bad roomate

Date: 8/16/2018

It started out with me (my younger brother and sister, mother in law and husband), we were in a house that seemed familiar to the one I live in now but in an apocalyptic setting. The zombie virus only made people act like zombies when they became starved, so it didn't seem like there were any zombies around; I should also mention I was the only one not infected. As i sat on top of a wardrobe i told my sister and mother in law that i was bored and tired of living like this so I showed them my arm (wish had a fresh bite mark) and told them how I got the virus voluntarily and they said they were angry and disappointed. Now for the roommate, I was coming back from some errand when I opened door to my room, only to see that all my belongings including my bed were gone.. and replaced with this dudes stuff. I asked him who the heck he was because I had never seen him before, and what happened to my stuff.. I specifically remember how angry I was and I could feel my heavy breaths. He said that my mother in law told him it was ok for him to move into my room apparently and his girlfriend walked in.. I got even more enraged because now there were 2 people I didn't know and also still mourning all my stuff. my mother in law finally gets home and comes in to see what's going on (by this time, we were all just yelling) she said that she hadn't even met these people and was wondering how they had gotten in the house. we then spent the rest of the dream telling at them to give me back my stuff and get the hell outta here, they finally left but not before the guy sighed and said that my stuff was in storage.. and he said he wouldn't be able to get it... I sat on my now empty bedroom floor.. just before I woke up.
