I have had an experience where, I'm aware what is going on around me, but I can't speak or move. It only lasts a few moments.

I don't know what this is. It could just be that my brain has forgotten, at that instance, how to speak and move. I have moments, all the time, when my brain seems to get stuck and I just can't do something, like zip my coat or button my shirt or lift my leg up a step. Sometimes I seem to forget how to swallow or even breath.

When it happens, my neuro-psychologist told me to kick start my brain by changing my circumstances. For example, switch to my non-dominant hand to complete a task. That seems to work.

It is so weird.
