Dream About Family Confrontation 2

I dreamed that Yuval, a cousin from my father's side who is in the reserves in the army, came to us together with part of the family including my grandparents and Iiti, a cousin from my mother's side who is six years old. Yuval started going crazy, went up to the room of Tomer, my little brother, where Ayiti was alone and tried to shoot him with something like that that releases poison. Everyone immediately went up after him and after they managed to take it from him he sat down on the floor in shock near the room. I immediately came to Ayati who was upset and crying, I picked him up and took him to the living room with all of us while I tried to calm him down. Yuval managed to take it again and threatened us all but we took it again. I said I was calling the police, my father didn't want to because that would mean they would take him to a psychiatrist and I said they should take him because what would happen on the rest of the holidays or if we wanted to meet is dangerous. Yuval wanted my father to address him but he was on the phone so he kicked him and they started a bit of a fight. Finally the police took him away.
