Skitzophrenia in dreams?

My dream, from what I remember, first started with me being at this small girls audition or something and my Sister was there, who is about 14, she was auditioning with everyone else, and there was a blonde girl there who thought she was the best at everything and very stuck up and it made me very angry so I kept repeatedly kicking her in the face beacuse she annoyed me so much, I then remember the police being called to the crime, as I clearly killed this girl, so I started to run away and I appeard at a weird shopping mall with lots of grass and concret paving and my old school teacher Mr. Munt (I know, funny name) walked past me eating an apple and for no reason at all I punched him in the throat and ran more.
It was about this time I had my new camoflarge hoodie/ windsheeter on and my hood up to evade the police, I was in a place called Morrisons (a UK shopping mall), standing far away from the entrance evading the police because they were searching the area because the audition took place around there, so I was standing far away from the crime scene with my hood up and people kept coming up to me asking if I was selling any weed, about 5 people came up and after all of it, I said no and told them to f**k off.
I then started walking across the car park and saw a mussly black guy I thought was my friend Josh, but it wasn't him because his eyes were to squashed into his head. The car Josh then got into sped off and up a cornor, crashing his car into a wall because they too were running from the police, I turned back to were they had been parked and they were both there, again, so I went up to the window and knocked on it, the person inside didn't look too happy and started chasing me, he caught up to me and started punching me in the face, the first time I had got beat up.
I was then randomly in a dark estate of houses with purple/ orange lights were the lights in the place had been on, but with lots of stairs and with my brother, who I'm quiet close to, we were running up the stairs and bumped into a few people who looked like punks, but they ran off and my brother dissapeard, so I decided to explore the area, upon exploring I found a friend's room/ house, her name was Anna-Bob and I know her quiet a bit in real life. We sat in her house and started talking for a while, then I suddenly appeard back at Morrisons near the petrol station and running from the police, they didn't notice me so I started climbing under planks of wood and dirt, upwards towards the street, as though the wood and dirt was on a slope, it was pretty dark by about now and the police were still searching. I popped my head up a little and saw two police cars, they stopped because I think they saw me, so I ducked down and nothing happened, but they stayed there, then my friend Anna-Bob was appeard calling my name from under me telling me to come out of the hidding place, by this time the two police cars unfilled with poilice officers and they caught me.
The second part I appeard back in Anna-Bobs room/ house and went to the toilet, which was my toilet in my house, and as I was sitting down the door handle started to open and so did the door about two inches, but no one was there, and I thought to myself about it, and did it with my mind, it was at this time a person whispered "Skitzophrenia" and I went insane with happiness, like an insane man would if he killed someone, with the look of mad happiness and psychopathicness on his face, that is how I felt, angry yet happy about what I just heard, angry about what I heard, happy about how I was feeling, really insanely happy.
That is the end of my dream.

I am 18 years old, live in the UK, smoke weed occasionaly, very paranoid person, quite angry because of my thoughts.

What does the skitzophrenia mean?
Thanks for all help.
