Zombie apocalypse

Date: 3/28/2018

At first me and a few people are standing in some opening and some NPC tells us that we have to kill the zombies. Some of us try to escape from this 'game' but its useless. Then a lot of other people appear and a few kilometres away there's a hard of zombies running our way. We all keep running in the opposite direction. We run up some hill where there's a really big hotel just standing in the middle of nowhere, I think it has over 50 floors. When I enter the hotel there's a hallway and a door on my right that leads to a sweets shop. Some people are staying in the hotel while others keep running on the path. I went up to the 30th floor and I was on the balcony of some room. I could clearly see zombies coming from a distance. The first time I dreamt about this my ex classmates were here and the second time my new classmates were there. I don't know how but some zombies got in the hotel and pure terror was unleashed. I watched as some people were fighting them. I woke up there.
