Question about fathers day?

I was a real daddy's girl and looked up to my father. He was my hero. My father died from cancer last year. I don't know what happened to me, but I always thought I would die if he ever died, but somehow, I accepted his death and often pray he visits me in my dreams which he always does. Thought I would spend my days weeping, but I'm not. Where did my pain go? Not that I want it. Is it normal for me to be at peace with my father's death or is there an underlying volcano waiting to erupt? Not a day goes by that I don't think of him. BTW I had a baby boy 3 months after his death. I had a great father and for that I'll always be grateful.
