About family

So I had this dream 2 nights ago that my dad had a sister which he doesn't but in the dream he had a sister and they were royal but my dad was the one to be throned but his sister was mad jealous and my brother never liked him so in the dream my dad's fake sister gave my brother a strong poison to put into my dad's beer and my brother put it in his beer and he passed out but he ended up waking up the next day but he was super sick so he was in a wheelchair but he asked me to take him to his favorite place which in the dream was an old hometown pond that we used to go to and when we went there my dad said goodbye and he faded away and I cried a lot in the dreams and out of the dream and my brother laughed and instead of his sister going to be throned I was throned but I still cried but i made sure to throw out his sister but my brother was who I was after but I woke up before I could kill him and then I started crying in real life. My question is what the heck does this dream mean, I mean like it makes no sense to me.
