I'm not so good at identifying dreams but I'd love to give you my opinions.
The fire could represent passion as in love, I could imagine that you loved that house where your parents live since at some point it was your home.
The burning could mean the total cleansing of something, like letting go completely of your old home.
Photos are the memories of moments that we have had and we want to cherish and keep with us forever thats why I think it was the photos that you decided to take not an electronic device or anything.
Then your parents telling you to start fresh could mean that perhaps there is something you could change or do differently for your future with your family.
I hope I could help you.
