Damn. I was about to say it was too cliché but then the father had dreams about it too. Thats pretty neat.
I'm betting that the reason the father was an ass was either 2 reason. 1 he got brainwashed by the girl, this is a fantasy, shit like that be happening. I won't shit on him for now. Or 2, ye he was just a dick of a guy, in that case chop his head off.. Yea..
Oh oh. Or number 3, he has mental breakdowns about his wife or something leading him into a deranged state of mind. Although this still makes him an ass, he's an ass with a slightly more valid reason behind it lol. Make him suffer but like, a little less..
