Is it normal that i daydream about conversations with friends?

Sometimes when I get distracted while doing work, or while I'm trying to go to sleep or while taking a nap, my mind drifts off and I unconsciously make up a conversation with a friend in my mind. Sometimes I can take part in the conversation and make decisions about what I what to say, and sometimes what I want to say just happens naturally. I think this might be because I want to spend time with those people, but even when I was younger and I had a lot of time to be with people, I still daydreamed conversations like these, and I actually really enjoy them. They make me happy like I am actually with the person. Except many times I would prefer that I had the conversation with the person.

Also, probably since I've done this for so long, the person in my dream is just like the real person, with the same personality I know they have. I'm also really good at predicting how these people act in real life because I know them so well.
