What is the meaning in a dream of sawdust

I dream collecting sawdust I wanted to lit the fire

Parking sawdust in a bag

I was driving down the street and I saw my brother and father outside of my dad's old house doing something in a tool shed. I pulled over and we went in the house which my brother now lived in. the house was being remodeled. Except for a couch in the family room there was nothing in the house in any room it was all under construction. It was covered in sawdust and Sheetrock dust, as was the couch. There was no kitchen there was red and gold colored tile on the floor. My uncle aunt and a couple of my cousins and a guy who i don't know myself and my youngest daughter, who is disabled. my brother was taking us around the house and explaining what work was being done. My father was playing with my daughter, then I remembered that my father had passed away 11 years ago and when i looked back to see him playing with her, she was just laying on the floor alone. Also my uncle who passed away about 5 years ago, he bumped me in the shoulder and made me knock into the wall where I got sheet rock dust all over me.
