If the death of your father and these relatives are recent it means that you just miss them a lot and dreaming about them is a way to still be with them.
If this has been a long time it probable means you can't get over that person and is having a hard time coping with this death
I don't know what type of relationship you had with your family but if it was suppose an abusive relationship you just might be traumatized by your past and can't get rid of the pain. Maybe to you dying was not enough of a punishment
if you believe in the super natural it could be he or they is trying to tell you something you should describe the dream and I could help you more.
Another supernatural way is that they are just letting you know they are there for you and are watching over you
