I was in a room with walls made of cement blocks and painted white, like in my school's classrooms. The walls roughly formed a square, although the wall across from me seemed to be infinitely distant, and a small wall extending to my right, as well as to the side of the player opposite to me. I, my classmates, and some other people were in the room, all siting in immobile desks. A giant ball was being kicked around, and there were teams.
I, as well as the player opposite to me and possibly others, possessed a gun that I thought of a sniper rifle. With it, one could shoot people, which disabled them for a time, the ball, making it move, or use it as a stick to hit the ball. After playing the team game for a while, we started playing free for all, and the person who had put the game together started calling out people's names, asking them to sing a song as they played.
I was in a warehouse and saw a person that I had never before met in real life, but knew from the internet. I greeted him, but he simply threw kitchen knives at me repeatedly, crying. I dodged the knives and tried to figure out what was wrong, thinking that he just didn't recognize me.
He questioned me, asking how I could dodge all his knives, and I responded that that was what I did, and I had become skilled at it.
