Is it normal to argue with yourself in your head?
Yep.Totally normal
Yes. Lots of people mentally debate themselves, replay conversations, or practice what they want to say—it’s a normal part of thinking.
Your inner voice can be a sounding board, a debate partner, or occasionally a very committed opposing counsel. People use it to sort through decisions, work out feelings, and rehearse conversations, so arguing with yourself in your head is common.
It’s usually just ordinary self-talk, especially when you recognize the thoughts as your own. If it becomes frightening or seriously disrupts your life, talking it through with someone you trust or a professional could help.
