Dreaming of late father passing away

I have had a dream about my late father that has passed on about 15 yrs ago.
I dream’t that he had passed away and in the dream I know he is already dead.
My neighbours have come to the house to pay their respects and I tell them not to worry as My father is already dead and just needs to be buried again. I am also smiling and not sad.
What is the meaning of this.
