A conflict within. [I Believe In Destiny]

I know this is gonna sound silly but these past few nights I've been having nightmares about my estranged ex-father. He walked out on me and my mom when I was 7 but recently, in my nightmares; he keeps telling me that I'm destined to become him and follow his lazy slob lifestyle. I try to run in the nightmares but he keeps chasing me.

When I wake up, I look in the mirror and see him, because with my ratty beard, I look just like him so I shaved it off..

But I just gotta ask. Is it possible to be destined to become your father? Because I always thought our destinies was our own.
