Agreed, I think it's perfectly normal as long as you don't think you're actually talking to someone (or hearing someone). I'll pace around talking to myself when prepping for a meeting - it's basically practice for the topics I know we'll be discussing. I even practice responses to what I anticipate their likely responses will be. It really helps because verbalizing something makes you think more deeply about how to communicate the idea or concept and will sometimes reveal gaps in your understanding or will reveal that you understand it but need to find a good way to concisely convey it to someone else who may not have the same level of expertise.
