Rosie hardest thing I've done was settling my dad's estate years ago...put off selling the house for quite some time then my sister and her daughter decided to buy it, a few years later they sold it and it broke my heart...it does get easier as I'm sure you know but right now just let the sadness be there...sound like you have wonderful memories with your brother, they will help for sure.
Your dream sounds like you not wanting to let go of things...you don't have too
