Scary zombie apocalypse in city

Date: 8/9/2019

I appeared to be in a large city and for some reason I was on top of the largest building and all I could see where people getting infected below me but then the building rumbled so it was about to explode so I jump of and for some reason I could jump really far so I kept jumping because every building was blowing up until I made it to the city docks where I found a rifle and then I went into the docks building and I saw a zombie staring at me but I didn't hesitate to open fire on him. Then when I did the dream ended with that building exploding.
