I'm a visual thinker and the images and video clips that run through my head as I talk seldom come in the correct order. For example, "I'm going to the store," usually comes through as an image of self, an image of the store, an image of the route, and finally a brief and quick video of motion through parts of that route. That translates directly as, "I, store, travelling to." I do a quick reorder in my head and correction of the verb as I speak.
This happens with everything I say, every time I speak.
When I get rushed or stressed, I make mistakes in the translation, and some odd things come out. Overly stressed or rushed, and I will swap syllables of the words, and jibberish comes out. A few years ago, my life was completely stressed out, and I wasn't aware of how stressed out I was, but my speech got very, very jumbled. I got rid of the stress and most of my speaking problems went away.
