Growling

I am in my room and I intuitively know the backstory of this extremely strange dream. At a certain interval of time, a different room, at random, in my house will begin glowing bright blue. Furthermore, any person in the room at the time would become a zombie of some sort. I seem to be the only person who knew this. I looked out of my door and saw my parents' room light up. Moments later my dad walks out and I slipped back in my room for fear of him seeing me. He went down the stairs and into our dining room, as did my mother. I go down the steps after them, making sure not to be seen. I as I come to the dining room, which is past our computer room, I see the dining room light is on and my dad is sitting at his spot at the table doing something, I cannot tell what. My mother is cutting coupons out of a magazine. I hear my brother coming and hide because I do not know if he is infected or not. He walks by wearing a blue cape and drooling blue foam, somewhat like rabies. He then leaves through the front door of the house. I hear a growl. It is Chelsea, one of my two dogs and she is infected as well. I run and she chases me. AFter a while, she runs out of breathe and turns back to normal. I think... maybe outrunning them cures them. So I got my other dog to chase me and the same thing happened. I realized that they were also a bit sluggish. Their stamina was greatly reduced by whatever this was. So I went to the door and walked out. My parents followed and I tried to run but it was like trying to run on the moon. I managed to get away from my parents but then I encountered my brother at the bottom of my driveway. He began chasing me and the dream ended.
