Is it normal to have no thoughts?
Depends.It depends
Yes, it can be normal to have a quiet mind or no inner monologue. People think in different ways, including images, feelings, or wordless impressions rather than sentences.
Some people have a running voice in their head; others don’t, or only notice it now and then. You may still be thinking without hearing words—your thoughts might show up as images, feelings, or a sense of what you want to do. A few blank, peaceful moments are normal too.
If you mean your mind has suddenly gone blank, or you’re having trouble concentrating or feeling unusually numb, that’s a different situation and could be worth checking in about—especially if it’s distressing or affecting daily life.
