My dream began with my Mum and Dad having a row. Both my parents have been dead for a number of years. 
In the dream I could hear shouting. I knew they were my Mum and Dad but they didn't look like my parents. My Dad was really angry. My Mum was shouting that everyone knew anyway. My Dad was getting more upset, and I was listening and trying to work out the reason for the row. 
Then the penny dropped, they were rowing because my Mum had been unfaithful and my Dad was not my real Dad. I just ran off, but my Mum saw that I had overheard. 
Its been bothering me since. My family has or had secrets. Does anyone have any idea what it could mean?
