Anyone else talk to themselves an extraordinary amount?

Anyone else talk to themselves an extraordinary amount? I'm a pretty reserved guy, don't talk too much mostly because of my stammer but when I get home the flood gates open and I just spew forth the most random shit all by myself. This mostly manifests in commentary of what I'm doing or explaining a thought like I am holding a TED talk. The thing is I literally can't stammer a word when speaking to myself so it's a real nice cathartic experience and blows off steam. No pressure to entertain or act confident. Idk it's a highlight of my days.
