lucid

I was sitting in the back row of my current Enlgish teachers classroom. All of the people who are in my class were turned, facing forward and completely quiet, though my teacher wasn't in the classroom. I was sitting sideways in my seat, and the boy I liked came in the room. He came to the back of the room and went to the teachers desk and leaned over it. He pulled out a knife and began cutting himself, and at a point he said my name and I looked up. He smiled, looking in my eyes, and cut his knuckle with the knife. My eyes went wide and I started shaking. I wrapped my arms around myself. He wiped his blood off on his jacket and gave me it. (I guess he thought I was cold?) He also dropped the knife he was using on top of the jacket. Then he turned and started walking toward the front of the classroom. I slipped his knife in my pocket, vowing to keep him from doing it anymore. I held his jacket, and turned the right way in my desk, staring at it.
He must have sensed something was wrong, because he turned around and crouched down behind my desk and asked me if I was okay. I said "no", and motioned towards his wrist, wishing he wouldn't have hurt himself. He showed it to me, and the cuts were just scars. That hit me as wrong, and I turned to face him, confused. I stared down at my shoes, still confused, and noticed they were a very old pair of shoes. I thought, "I wish I had my Converse on." and then they were my Converse. The guy I liked was staring at my shoes too, apparently, because he said, "Your shoes just magically changed.."
That was when I realized I was controlling my dream, and I just said, "Yeah. That was weird." And he nodded.
There was more to it, but I've forgotten it.
