Is it normal to argue with people in your head?
Yep.Totally normal
Yes, it’s normal to replay arguments or imagine what you wish you’d said. Your mind may be rehearsing a conversation or working through frustration—even if it gets a little theatrical in there.
Lots of people have imaginary arguments: you revisit something that happened, prepare for a conversation, or finally come up with the perfect comeback three hours late. It’s a pretty ordinary way of sorting through feelings and possibilities.
It’s mainly worth paying attention if the arguments feel relentless, upset you, or get in the way of sleep or daily life. Otherwise, your brain is just holding a very busy meeting without inviting anyone else.
