Why do I keep having imaginary arguments in my head?

Ghost talk. So many times we get into conversations with people and we regret what we said, or we wish we would have said something different. Likewise we will foretell conversations that we're going to have and begin to map out the dialogue of the other person and how we're going to respond to it. So both the regret from the past and the regret from the future conversations, and we try to tackle or navigate what we would do better. But the great irony is, you'll have somebody leave work, get into a fight with their boss, leave work, be driving home, pull up to a stop sign, and they'll have a crazy person on the side of the road. And the crazy person will be yelling at the stop sign and arguing with it. And the person will just roll up their windows and lock the doors and say, man, that person is crazy, they're talking to somebody who's not even there. Then they'll drive along and pick right back up the conversation in their mind with their boss, who isn't there either. See, we normalize this kind of ghost talk. We're talking to figments of our imagination, people who are not there. The reality is that conversations do not play out how we think they will. No matter how many times you rehearse what you want to say, what the other person's going to say, whatever else, you're constantly in a fantasy. You're in imagination land. You're not in reality. When we circle back on the first point of being present in the moment and in a state of prayer, that is the best thing that we can possibly do to tackle any conversation. When all of my mental ability is not on some preconceived notion of what I think I'm going to say or what the other person is going to say, but I'm completely present and focused and ready to engage that person on exactly whatever it is they bring up, I am in my best place. It's like the dreaming about a fight is not the fight. The fight is the fight. And the best way to be in the fight is to be completely present and focused, ready to dismantle whatever is said that is untrue, and ready to build on whatever is true. We must be completely mentally aware and have all of our senses trained on the present moment when we are interacting with the people around us.
