What on earth could this dream mean?

i had skipped school because i didn't feel good but i think i went somewere and was caught and sent to school, only school was crazy, when i got there me ad the cop who brought me there was trying to figure out what was happening, there were 4 rows of students on the ground, 2 faceiing one way he other two faceing the other, inwards towards eachother, and theye were in a cage like thing outside the front office and out of the blue they all sat up and started shooting eachother dead and then stopped. then it was like the scenes changed and i was next to two kids with a gun in my hand, there were those little red lights that come from guns when your targeting someone everywhere, from everyones gun we were all in a mash pit killing eachother, one of the two girls i was with asked if there was a red light on her yet, the red lights were on all of us and kept moving around, there was a light and we both said yes, then there was a random girl with a book in her hand saying that to stop these games we have to kill the one who started it, and at that moment thats hwen the games resumed and me and someone else shot the girl, only mine missed her but the other persons got her, she stood up and walked to her car i followed and was asking why she started all ths what was the point and she got in the car in a state of complete shock at being shot and said she didnt it wasn't her and i looked back at that huge cage filled with students and guns and those red target lights and woke up, what the hecj could this dream mean? ive been having really weird dreams all week like intensely weird dreams and im thinking theyre trying to tell me something haha
