Mortal Instruments dream

I will say before I go into my dream, I don't exactly give very long descriptions of it because I don't remember everything.

My dream, I just remember it starting off where I'm in this church- it seems like a church- feeling scared even though I keep telling myself to put on a brave face. So I start to roam around whenever I hear the shout of Clary, my name in the dream. So I'm just like: oh shit! SHIT NOPE.
I'm not quite sure if I had a limp or not but yeah.
So I remember running up a set of stairs and opening random doors trying to figure out how to get out of there. So I run into a random room and I keep hearing Clary's name being shouted, over and over again. It's a deep voice and I'm just thinking I have to get the hell out. So, going through that door, I see a set in front of me and I can clearly see the outside so I make a break for it and run. I get out of there and run all the way back to my place or the institute but on my way running I catch up with Simon. I grabbed his hand and we quickly went back to someplace where Jace and Alec and Izzy were. I remember that I was in a car with Simon and probably Luke or Jocelyn when Sebastian pulled up with some girl that looked like "me," AKA Clary. He did a double take seeing that I was in the back of the car, so I assumed that I had been trapped in the church place because of him and that he was the owner of that voice.
He growled and said something like, "You are my sister and you belong to me! You're my girlfriend. You disobeyed me!"
So me, being Clary, hopped out of the car and shouted something like: "I AM NOT YOUR GIRLFRIEND! I hate you!" He basically had drove off though when I got out of the car and I heard Alec and Izzy say, "Clary, get back over here! It's not worth it going after that asshole!" 
I remember storming after him otherwise and my boots sinking in mud since it had rained.
Jeezus.
I have weird dreams.
Although, I liked it because I haven't ever had any type of TMI dream. I've had a Vampire Academy dream though c:
