[Blazingdisregard]

this mean? I had a dream that i went to school with a gun and a knife in my pockets.In the dream,I was walking down the hallway of my school when all of a sudden there was a big commotion,and kids started screaming and running in every direction trying to get away from somethin.It turns out,some kid had brought a weapon to school (i can't remember if it was a gun or a knife) the security guard at my school shot the boy before he could hurt anyone.The boy was laying on the ground and i ran to him,kneeled down beside him to see if he was okay.Two of his friends were there too,and one of them screamed at the security guard "you just had to take his life,didn't you?" after the halls cleared,the principal,assistant principal,the police,and the other security guards go around asking students and teachers about what happened.I got questioned too,and the whole time i'm talking to them i got a gun and knife in my pockets and i'm scared their going to search me,but they don't.This dream really really scares me,and i'm afraid it's going to happen in real life.I was so scared,i was thinking about bringing a knife just in case,but i know better.But i'm real scared,what does this mean?
