What's with the blankness?

The brain showed a blank mainly refers to the sudden pause or disorder of brain thinking in some environments, so that the ideological consciousness and other performances showed short-term obstacles of varying degrees. This situation is easier to show in extreme environments, external stimuli, and more easily in people with poor psychological quality, mainly due to fear and anxiety in extreme environments, which makes the body's autonomic nerves excessively hyperactive and affects the brain's thinking function. The normal functioning of the brain itself has been delayed, and the body's defense against the outside world will be slow and lead to danger. Severe patients may show absentmindedness or even syncope, and need to stabilize their minds in time to return to normal.
