Dream About Lost City Chased Zombies Survival

I only remember a little. I was lost in a city that was unfamiliar for me, I was going to a destination, I don’t know where and why I am going there, but I took something with me which is important, and my guess was that was a thing I need to deliver, as later when it turned nighttime, things got scary. I was suddenly chased by three people. The first one came in front of me but he suddenly went back. I turned around and saw a person in a black hood was chasing me at a high speed. I wasted no time and darted the opposite way. Suddenly there were 2 black hooded person in front of me, charging right at me, but I swiftly dodged all of them. Then i forgot what happened, and it suddenly changed to another scene, where there is a zombie outbreak and I was skydiving into a city, looking to survive. I saw my best friend and we both got guns and we started surviving together like in the hunger games. The city was very high tech like those in sci-fi movies.
