At the park going around riding a bike, (bmx bike) then I went down mainstreet and saw some girl that was doing something strange, (I don't remember exactly what she was doing that was strange, something that indicated she was a robot or something like that)
I had some rope that I swung around and snow came out. (no idea why this made so much sense in my dream) I was swinging it around and getting snow on things, I forget the reason that I needed to get snow on stuff. Then I followed the girl up some road that went up a hill. There was some other stuff that went on but I don't remember what.. Next scene I was back the road to my house in my moms suv, we were going towards the highway (me and some other girl, it wasn't claire or the girl from earlier) that I knew for some reason was a bad guy and was following, the girl driving the car was probably in her 20's and she had darker color hair, she was my partner for right now and we were following the robot girl from earlier. The car ahead of us pulled off left on the highway and started gong down away from town. But we turned right, I got confused and looked over at my partner asking her why we weren't following the car. She said something and I realized that she was really an enemy that was supposed to kill me, she started swerving the vehicle back and forth really fast and I had to lean over and grab the wheel to keep us from crashing. She punched at me and was obviously going to try and take us into a brutal crash at 70+ miles an hour.
I then remembered that I keep the dagger in the side pocket of the passenger door and grabbed it.
(I keep one there in real life, mainly because that's the only place that I won't lose it) I get it in my hand and get ready to stab her, but all of a sudden I have a really hard time stabbing her, I hesitate (only for about a half a second) and think that she is my partner and really pretty and I would hate to kill her, that we've been through so much together and... I force those thoughts out of my head and stab the dagger into her neck.
(one of the things that I remember is the sound of it going in and going through her windpipe.. that'll be something I remember for a long time to come )
she struggles and is obviously in much pain, she begins to cry as she struggles for breath. I feel really bad and almost cry too but I am so desperate to save my life. The vehicle is slowing down a bit on the road. I look at her, she looks so helpless right now I hate it so much, she looks at me and I can just tell that she wishes she was really on my side. (I am flooded with false memories of things that we did together and missions that we completed)
I look down at the dagger which has blood all over it and look back at her as I get ready to stab her again to kill her.
"Sorry." I say and I plunge the dagger into her heart I see her eyes get wide and then she goes limp. There's blood all over me and the seat.
I wake up shaking and disoriented.
