Thanks raging vortex. He died about 30 years ago from cancer.

In the dream, no, I didn't get to say goodbye to him before he died. In real life, I did get to say goodbye by accusing him of being a terrible father to me, for which he apologized.

Oh, well, my entire family hates me now. Have for a long time. My sister treats me like you would a good neighbor but none of my cousins makes any effort to stay in contact with me. And a few of them I have never got along with.

Not sure why I'd have this dream about my father. Very strange.
