Never been close to my mom

I don't have many memories of her before my parents got divorced (age 7) but I remember feeling like she was my security. My dad, on the other hand, was the 'bad guy' (at least at that time).

It's odd but I remember being very young, maybe 4, 5 or 6, and having a somewhat prophetic dream. I had asked my parents if I could sleep in bed with them and my dad said no while my mom said it was okay. They argued but ultimately I was allowed. That night I had a distinct dream where I felt and saw that my mom was leaving. What it meant I didn't know, but I woke up crying. My parents asked me what was wrong and I said I had a dream that mom was leaving. "Leaving? What do you mean? Going where?" they asked. I couldn't answer. I just said: "Leaving, go away. Are you leaving mom?" She said "No" of course.

Following her actual departure, I had a very different relationship with her. She wasn't really apart of my daily life. I would spend time with her on the weekends. She was not really a motherly figure for me. Today her true character is a bit of a mystery to me even though I see her every month at her house.

I'm 25 now but I still wonder how this all affected me. Is it normal?
