Think you're over analysing with the dreams, plotlines etc. I mean the first episode starts out with them in the parking lot of a club where a shooting takes place, and they get arrested and released within a matter of hours. Other scenes involve an invisible car, a black justin bieber and a drug deal shootout in the woods.
It was meant to be surreal, but the underlying constant is how real the characters are. Earn is literally struggling to eat on a daily basis. Has no fixed address, his relationship with his family is distant at best, relationship with the mother of his child is as inconsistent as his pay days, and Paper Boi knows he's leeching off his recent success but also knows he needs Earn around.
It was made for the culture, black representation, hip-hop etc. It's not made to be dissected like Westworld.
