sibling rivalry nightmare

Date: 8/26/2018

I have 3 younger siblings M,P and G. in this dream I was arguing with my Dad, then I came and say up at the table saying something like "I CAN'T change my mind. " Although then I had the thought (my more mature self) saying "that doesnt mean it won't change. " meanwhile M and G were physically fighting behind Dad's back. then P came in and I got scared and jumped up to intervene. P and G were pulling both ends of M. i thought "I have to save her she's a mother. " pulled the knife out of M's hand. she was grateful, even though I took her weapon, she was helpless.
