Dream I was shot at, what does that mean?

last night I had a dream that I was on fecebook and somehow found out that my teacher along with another adult wanted to kill me and 5 or six others

in my dream I went to school and we where sitting in morning assembly when he pulled out a gun along with another teacher and they attempted to shot me but numerous time the guns trigger failed

something happened to the second shooter about halfway through the dream I'm not sure what happened though

as tge other person continued to shoot I tried to hide behind my friends and other people in the room but they acted as of nothing was going on as I squatted behind them in fear

in the end they stopped trying to shoot me because I had knocked them to the ground but the weird thing was when I talked to people at lunch (this is still my dream) they seemed to not know what I was talking about

except for one other person

I've recently had problems with two of my best friends who were mad saying I was mean and acting like a ***** and one of them tried to apologize but I don't want to talk to anyone about it right now and was wondering of it had anything to do with that maybe
