Has your therapist ever said this to you? What does it even mean?

My DBT therapist said that last week and I just saw someone in another thread say that their psychodynamic therapist said it. I can't imagine two more different types of therapy than DBT and psychodynamic therapy. So those must be two different processes we are supposed to trust. But why should/would we? I also had a professor say that to me once. Or maybe twice.

I think maybe it comes up when I ask someone a question that they don't know the answer to, but they don't want to just say "I don't know." But it annoys me.
