So, i hate my dad for personal and family reasons. My parents separated a long time ago but I used to visit him. I don't visit him anymore because of an argument that got physical.
Basically, if I had a "get out of jail free" card, he'd be the one I'd get rid of.

Anyways, the dream starts out just in the middle like most.
I have a gun and I'm walking through a long white hall with unrecognizable people on the sides. The walk takes a while but the door is visible at the end of the hall.
When i reach the door, and start turning the knob the dream ends. I have a feeling in the dream that my dad is behind the door but i never actually see him in the dream. I know i'm going to kill him but i never see it because the dream ends when i turn the doorknob.

Why am I having this dream?
Its been on/off for a couple months but i cant make sense of it
