This dream seems to be about nurturing issues - a need for nurturing or a need to nurture. And it seems that whatever this nurturing issue is, it either involves your mother or originates with her in some way. It could be suggested that you are being distracted from getting, or giving, the nurturing that you need, that maybe you feel misunderstood or nervous/anxious about this issue for some reason. Or possibly "nurturing" could be replaced with "responsibility". The grave/graveyard in your front garden suggests that this issue concerns "buried" aspects of self which need to be acknowledged and tended to, as a matter of your growth.
Is there some kind of anxiety in your life concerning trust or responsibility?
Do you feel like you are hiding your true self?
Do you need to work on cleansing yourself of hindering aspects of your personna or attitude?
Is there an issue where you feel in the right, and you are overlooing consideration of others? Or maybe you are not receiving proper consideration?
What do you think?
