My Worst Nightmare

I used to have dreams every night, very vivid, lucid and constant. There is one nightmare I had that sounds pathetic, but it destroyed me, I spent months only thinking about this nightmare, and I stopped having dreams after it. Now I hardly ever dream, maybe once a couple of months, or when I take too much Melatonin.

Before starting with the dream, I want to give a bit of context with the people involved.
Both my parents split when I was around 3-4 years old, and I don't think I ever seen them talk after that. I remember how my dad left on his car, at the time I wasn't aware he was leaving for good.
Some kids from split parents want their parents to go back together, but I never had that urge, never seen them as a couple really, they are just my mother, and my father. Of course I am close to them but never had that vision of a loving couple of them, maybe I was too young to build this vision.

For some unrelated motives, some years of my childhood I spent with my dad, and some others with my mom.

When I lived with my dad, I always tried to impress him, I wanted to be the perfect son to be proud of. I was always the kid with better grades, the winner in all competitions, the top athlete, the kid that fixed everything at home.
It was very important for me, as a kid, to impress my dad, to make him proud of me.

I remember the first time my dad told me a silly dad joke. I remember laughing a lot at it, and seeing how happy that made him, made me incredibly happy. I don't remember which joke he told me, but it was in a car ride to somewhere, and seeing his reaction to my laugh was so special. I believe it was because everyone got tired of his dad jokes, but me laughing at his silly joke made him happy.

Everytime I said a silly joke, he made his best effort to laugh at it. I believe he wanted to give me the same happiness I gave him when he told me jokes and I laughed every time.

Okay, so back to the dream.

I was landing on the airport, maybe I was around 10 years old. I was alone traveling, at the time I had traveled alone multiple times so it wasn't anything scary.
There, I met my dad and his family, we get to the car and he starts driving home.

I do not remember anything about the conversation, but it reaches a point that I make a silly joke.

Silence.

I look at the center mirror to see my dad's face, zero emotions.

Nobody laughs, or talks, or makes any comment about the joke.

I wake up and cry. Remember this for several months.
I know it sounds silly, but this completely destroyed me. I never disappointed my father, I was always his pride, what did I do that disappointed him?

I haven't talked with my dad in about 14 years I believe.
