Is this healthy or unhealthy for me??

So I got a question, I don't know if this is like daydreaming or anything close to it, but in my head on repeat I make like conversations in my head with my favorite characters from games or anything I have watched or read and try to make them the most accurate to the personality I think they would act in that scenario and maybe a little out of character or but most of the times I just make characters I really like, react to my daily life just as if they were in a reaction video but I also make myself the narrator. I can't never actually stop with these scenarios unless I am actually like doing some hard tests or something that is hard for me and I really really need to think. I think I started using it as a coping mechanism because I am alone most of the times and I don't really have friends who talk to me all the time. But could maybe someone explain to me what is this? Or how to maybe control it since like I don't wanna do it but I still do it even tho I am around someone and it's annoying even tho it's all in my head and I never say out loud what currently the characters are saying in my head. I am so lost on what to do😭😭 (also I don't know if I posted this into the right group so if it's not in the right group please correct me)
