Is it normal to talk to yourself in your head all the time?
Mostly.Normal for most people
Yes—having a running inner conversation is normal, and lots of people think in words much of the time. People vary, though: some have a quieter inner monologue or think more in images and impressions.
Your inner voice can help you plan, sort through feelings, rehearse conversations, or simply narrate what you’re doing. It may feel like talking to yourself, but it’s still your own thoughts—and there’s no single “normal” amount of inner chatter.
If it becomes distressing or disruptive, or seems like a voice that isn’t your own rather than your usual thoughts, consider talking it over with a mental health professional.
