Concert to real life zombie game?

Date: 6/8/2020

It starts out with me on stage at some concert with this other girl who was there to preform. Everybody came to see her, but for some reason I was on the stage with her to sing as well. I didn't know her or really know of her. Songs that played were already existing songs and what we'd do is as they'd play we would sing them in the style of the person who originally sang them, and lights would shine the original band's logo and a large clear ball with the logo on it as well would drop from the ceiling. Soon a song came on that I didn't know so I whispered to her that I didn't know it and she seemed upset but we skipped the song. I just remembered the song that came on was the theme song to the anime Fire Force. I told her I had never watched the anime so I didn't know the words to the title song. The next song that came on I didn't know either but was too scared to tell her cause I didn't want her to be mad at me. It skips from here to is in a room not far off from where the stage was. She was showing me and one other person how to work the controls of the game we were playing. It was like full dive sao style virtual reality or something even though we didn't actually dive into anything because things popped up like menu screens and buttons to push and stuff but I didn't have a controller. I had never played this game before and she seemed familiar with it but she wasn't really giving me any tips. We had guns and stuff and zombies would come at us (they looked pretty gross) and basically we just had to navigate the rooms and kill them and capture certain zombies. I guess other players were playing as some of the zombies. I killed a few zombies which was just me panic shooting them as soon as I saw them which worked somehow. I remember going back into the original room to find the girl and asking her how to reload my gun because I was low on bullets. She pointed to a spilled over sack of vegetables on the floor and said that I could use those. Turns out pressing vegetables to the gun reloaded it somehow? But she said I could only use half of them cause the other half was for her. I then asked her how to pull out my gun because the other times I did it by accident in a panic when the monsters came so I didn't actually know how to do it. She said to pull my middle finger towards my palm so hard it felt like it would crack and then the gun would appear. I did what she said and my finger cracked but the gun didn't appear. She thought that was strange and told me a few other things to try but they didn't work. I think we figured it out somehow though cause next thing I remember is sitting on my knees next to the vegetables trying to reload my gun and using some of them hoping I did it right. Another creature came up that was quite short but long and it took a lot of shots for me to kill it. I then realized I had used the ammo vegetables wrong and hadn't given myself any extra bullets at all and had instead used them to upgrade other stuff. As I went back to the vegetables I was surprised to find most of them were gone and realized she must've used them. As she shouted and I looked to see that a large boss was appearing across the hall I quickly grabbed a few french fries and pressed them to my gun and gave myself a few extra bullets. We quickly realized we were outmatched though as the boss charged up a big laser to shoot us down with. With nothing else to do the girl dropped to the floor facing away from the monster and covered her head, knowing she wouldn't survive the blast. I quickly ran over to her and covered her slightly but mainly plopped down next to her to accept my fate alongside her. I closed my eyes tight as the laser was fired and I felt my whole body getting very hot. I felt like I was burning, and an area especially in my lower back felt the worst. I thought about reaching back to cover it but realized there was no point and told myself it would be over soon. Within seconds my body grew much hotter and I was no longer able to breathe. I laid there wondering if I was dead. Then it skips to me standing outside the building reading comments from people who attended the concert trying to find any about myself since I was a guest but I couldn't find any. That's the last thing that I remember.
