dream fragment

I just had an extremely unsettling dream. I was put in a mental hospital [ considering I do have depression issues irl ] and we were put in groups of ten kids. The whole hospital just seemed like a big elementary / middle school.. our 'teacher' was a huge bitch.
I remember my good friend August was there too, strangely.
We were on our way to go to a pool, I guess, and me and a friend I had made there trailed behind. Weirdly, the 'friend' was someone I used to hang out with as a kid. Her name was Jordan. Anyway, Jordan and I were talking, and she persuaded me into a plan. A plan to kill the teacher and escape this hell hole.
We went through with it, and she killed one of the other 'students'. We ran outside with August and another unknown male and I saw my mother. another kid ran out and yelled at us, telling us that the camera's were on, we're gonna go to jail. I wasn't taking part in killing them so I figured I'd be okay, but Jordan decided it was best to kill ourselves instead of get charges pressed...she pointed the gun at herself and killed herself. Then August took the gun and pointed it to me and said something along the lines of "It's for the best, Hayley, we'll miss you".
I tried to tell him I'd take the charges and he wouldn't listen. I waved goodbye to my mother and turned around, putting my hands up and closing my eyes. I was shot and I fell to the ground.
The most unsettling part was that I could feel myself being sucked out of my body. Leaving it. I could fly now. I remember also praying and apologizing to God [ even though I don't hold a religion and I was previously a Satanist for good reasons ]. I remember looking at my mom and she didn't cry.
I kissed her on her forehead and thats when she started crying, even though she couldn't see me. I guess my dog, Sasha was there too, and she was whimpering and staring at me and trying to lick me and I pet her and kissed her forehead too. then I woke up crying and my hands were dead cold [ and my hands are NEVER cold ].
I have no idea why I had that dream. ):
