Another dream: about intense anger

Yesterday I had a dream. I was walking with my family, as in mother, daughter and aunt. We were then walking through a school ground and all the children were playing on it. There was some kind of uneasiness within me like I felt the kids were rude. Then I clearly heard on girl saying  (forgot the exact sentence, but it was to my daughter falsely accusing of breaking something, but I got pretty worked out hearing it). I was surprised and angry with the creativity of making up something like that. When I turned around I saw a very little girl and my anger even grew. I held her ear and was firmly pinching her and swing to her, how do you come up with such things. For a second I felt good about expressing my anger and was thinking I should handle every situation like this.
Then within a few mins, there were teacher and possibility police around. They called me to meet them. Then I said to my aunt that there has been a problem and please accompany me. I made my mom and my daughter go home. The meeting was in a park, I left my purse and asked my aunt to keep going I will join her after getting my purse. When I went to take the purse, I saw mom had left and left my purse there. Thank God, I came back at the right time to find it. Also, I saw my daughter had puked.
Just then I woke up and the first thought was I should have complained to a teacher instead of handling the matter myself. It was similar to the situation I was in before, where I took my daughter's classmates to home without informing the teacher and thought that informing the parents is more than enough. And unfortunately, his parents didn't lift the phone or siding see my messages.
