Is it normal to talk to yourself in your head?
Yep.Totally normal
Yes. Thinking in an inner voice is a normal way many people process ideas, plan, and make sense of things.
Lots of people have an inner monologue: they silently talk through plans, replay conversations, or give themselves a running commentary. Others think more in images, feelings, or abstract ideas, and many people use a mix. There’s no single right way for your thoughts to sound.
