We do a lot of things on auto-pilot, not really thinking about what ae are doing, but if for some reason we doubt our action, it's really, really difficult to remember how to do that action. If I had to tell someone how to drive my car, I wouldn't have a clue how to explain which pedals I press and in what order, but my brain does it automatically. When I take a certain journey, I don't have to think about directions but if I actually try to remember that route, then panic can set in when I can't remember the fine details. I think a lot of these panic blank episodes come when the brain, for some reason, tries to switch from auto-pilot to actual thinking mode. Anyway, that's my hope!
