Reality bend

Like most dreams you are the main character but this one was rather interesting. It started off as a bunch of people playing a game. The objective was survival. I was hiding in a room when someone burst in. At first he didnt think I was playing but I "hit"his stomach he smiled and replied "you are playing! Pow pow! Your dead." Aparently warrior wasnt going to win in a game with finger guns. So I fell to the ground like a game of "no bones" and he looked at me weird looted me and went on his way. Many people looked at my body and commented that I didnt have to stay dead in such a manner but I stayed silent and they eventually went away. Upon starting the next game I went with magic class and somehow turned into sailor mars (at least the outfit). I remember going up against a girl acting the same exact character as me but the game ended before the fight concluded. I met up with my sister and we roamed around the rather large neighborhood deciding it'd be best to go home soon since it was getting late. Soon chaos started happening and buildings were on fire. My sister and I got separated somehow and by the time I found her she'd changed into something similar looking to a husk from mass effect but she kept insisting we fuse together. I ran away, not knowing how to save her, I ran.
After a couple months of not returning to the spot my sister was, I'd done a lot of research and met up with another person like me. He just wanted to know what the hell was going on. By this time I knew and wanted to show him so i took him to the place my sister was pretty much haunting. I told him to keep hidden and stepped into the room (it looked like a conference room with a wall of windows on one side and a projector screen). As my sister appeared in her purpleish almost dead biotic way she asked me if i was ready to finally fuse. I said I was and this apparently startled my hiding comrade as he reviled his location and starting running towards me, it was too late though. I held my arms open wide to my sister and just as we were about to embrace and her purple haze surrounded me i broke the chain on my neck. The tags that were attached to it flung to my sister like a magnet upon being released and she stopped. There was a hazy look in her eyes as I stepped away and she started hugging herself lovingly.
"To think it was the tags the entire time" I said. "They are the key to survival" "Wait what do you mean?" My companion asked but all I could do was smile as a bright light shined on me and I started to fade away. "You'll see!"
I took the headset off that had the alternate reality in it. I was in a place like a library. I stood and went to the receptionist. "Congratulations, you made it!" She said happily.
The point of the game was to present a person that you care deeply about in a way that you had to save them from themselves. You just had to find the key (which was a necklace like dog tags you always have on you in the game) there are subtle clues throughout the game pointing to the tags being the key). If one did not save them (aka they just killed them) the whole process would start over and the person would think they just had a weird dream. It was in an effort to find a better way to do things rather than kill, to make the world a better place.
My real sister then walked up to me welcomed me home and we went out for ice cream. On the way out, I passed by a boy taking off his head gear and we smiled at each other
"See you later comrade"

Just don't want to forget this dream :)
