I had a dream last night

I had a dream that I, and some of my classmates in high school, had been kidnapped by a certain organization and put in some kind of death game for training. We each had some sort of special ability, and mine was to be able to see into the future. Unfortunately, I learned that the organization that was trapping us has another way to see all of our futures, so no matter what I did to change things I couldn't escape, and was only able to win.

Once I had won (I think using a grenade trap on the last guy) I was giving a mission to assassinate the king. I guess the location I was in had changed at some point in my dream. I now had excellent stealth abilities, and really just had to hide in a corner and shoot the king. I fired about 16 arrows into him, but that wasn't enough to kill him so he soon cornered me and, once he determined I was an assassin from the organization that had taken me against my will, offered to play a death game against me where the loser in a game of scum would die...

I kept losing for awhile before I used my ability to see the future and saw that there were no instances where I won. My alarm them went off and I woke up. Now that I'm awake, I'm certain that the king was cheating since it was his servant acting as a dealer and the magical contract we were using basically operated off of the rules of no game no life regarding cheating.
