Cerberus

I was in high school but it was built like a prison.
I attended some lessons and stuff, going to class but we had cells in one wing of the school. I was running to get to my cell so that I could grab some PS3 games to give to this younger kid who had a way of sneaking into the solitary confinement wing, so he could smuggle them to my mate, who was in there at the moment.
I had to quickly run into this basement where there was all these old doors and spiderwebs because for some reason the game disc I thought was in the cover I gave to the smuggler was actually down here. I ran to find it and when I did I ran to bring it to the smuggler before it was too late. He wasn't very pleased that I could get him busted by behaving so recklessly.
I then went to the gymnasium, and I met some people there who were doing a dance class and realised that I was actually a part of it and I knew the moves. We had to line up in some order, I couldn't actually divine how the order was chosen but somehow I just knew where to stand. I then turned around and saw that there was a whole crowd of people sitting there watching us and this was actually a performance! The music started and we had to start dancing, I absolutely sucked. I knew the dance moves because I could remember learning them, what I couldn't remember was the actual routine itself, I had to try and imitate the girl next to me, who it seemed was in the same boat as me.
we had a quick break for some kind of intermission and we sat down cross legged on the ground facing each other and
she looked at me and stated, "I don't know the moves properly."
I said "It's okay, I know the moves, I don't know the order they go in though. You're doing better than I am."
Her beautiful eyes that were previously on the cusp of tears brightened a bit at that and she gave me a little smile, I gave her a small smile in return, before looking away.
Suddenly there was a big commotion and there was car crashes and explosions all around and police were running through the place.
I grabbed the girl by the arm and I ushered her over to this wall and we sat against it out of the way of the drama, our backs against the red bricks.
She turned to me then and asked a question, "Is it true that you got 15 and 4?"
"Yeah," I responded, "it isn't what you know, it's who you know and how good a deal you can get." (please note, I don't know what this actually is)
I then spotted a person that I knew in the dream, but not in RL, get hit by a car. I looked again and there he was standing in the middle of the road, he was alright. Until a car hit him, the same exact car I had already seen hit him. I saw a lady run around some cars and run into four police officers who then proceeded to bash her. Then I saw it actually happen and I realised that I was seeing a little bit into the future. I could probably change it, I thought. I then had a vision of the girl I was sitting with getting killed by the largest man I have ever seen in my life, he would have been at least 7 foot tall and he was so muscly.
I turned to the girl beside me, who I had by now realised was an old partner, even though she didn't resemble her at all, I knew that it was her because I knew her eyes, and said "I want you to go and stand over there at the end of the wall and whatever happens don't come back this way and don't look back.
I knew that the man was going to come this way and then look for her. I knew that it wasn't going to end well for her, if he found her. I saw him coming and I told her very forcefully to go. She looked a bit upset and scared that I had spoken to her in such a way and it tore me apart inside to do so.
I turned to face the direction the giant was coming from and there he was right in front of me. He tried to shuffle me aside but I refused to move and then he tried to push me but I turned with it and swung a leaping right hook at him connecting with his jaw. He then turned to look at me, he had a murderous look in his eyes. I knew then that I was going to die, I knew that I had saved the girl though.
The man mountain toyed with me, he threw me around like a rag doll and I was broken and lying on the floor when I saw her again she had decided to peek around the corner and see what was happening. I gave her a smile with what was left of my wrecked visage and she cried. I looked a the big man who had picked me up and was readying himself for the coup de grace, he had a vicious sneer and I poked him right in the eye and he dropped me and stumbled away a little bit, screaming in pain.
My broken body hit the floor and a jolt of pain almost drew me into unconsciousness, I fought to stay awake. I saw my old partner run over and she asked me why I didn't run with her.
"Because he was going to kill us both, I saw that there was no other way of keeping you safe, if we ran together he would have caught us, so I thought it safer to distract him while you ran away." She cried, the tears flowing unchecked down her cheeks. I then whispered, my strength failing, "You had better go, I am going to die tonight. Please, don't let it be for nothing, run away."
She didn't want to believe it but I am sure that she knew it was true because the next time I told her to run she gave me one last kiss and turned to flee. I watched her back as it got smaller and smaller as it got further away from me.
I was suddenly grabbed and hoisted into the air. The giant had returned and he was irate. His eye, where I had recently decided to place my finger, was bloodshot. He then said "You're going to be famous, all over the news tonight, little man."
He then placed one of his giant hands on the side of my head, it was turned in the direction of my receding ex partner, so I saw her one last time as she glanced back. I then felt a rush of momentum as the brick wall quickly approached my head with the intention of dashing my brains against it's hard stone and mortar. I smiled as I saw her round the corner at the end of the wall because I knew now that she would be safe, that was when my head met the wall and I woke up.
