Bad dream any idea what it could mean?

i had this talk with my younger brother last week and we argued morals. Right from wrong and at what the cost it can be to do the right thing. we talked for around 2 hrs. i felt this was open conversation (not one side doing the talking and the other just listening) Last nite in my dream we were the same age and we were outside a school. he was talking to some kids and i was keeping an eye on him from a distance. i heard some kid ask him to say what he saw in front of a crowd. he agreed and they walked into a courthouse. i later walked in to hear the verdict. a man was guilty of drunk driving and manslaughter.as the court was dismissed and everyone was walking in one direction outside i couldnt find my brother. i figured i should head to the front of the crowd so he would have to p me thus finding me. when we saw each other he was towards the front of the crowd around 12 people me being 13th. he said that he didnt think talking (telling the truth) was the smart thing to do. i pondered this as we were walking. another person was with us walking and he threw up a gang sign kings i told him we dont claim that **** ( gangs) (anymore anyways) and i saw him causally going to attack my brother so i fought him and knew it would be a challenge to win but i got him down and was weak. i kept trying. i woke up trying. what do you get from this dream. i have an idea but want to explore futher
