stun
This word describes a sudden interruption of consciousness or cognitive function. In a physical sense, it refers to a temporary state of paralysis or disorientation caused by an external force, such as a blow or an electric shock, leaving the subject unable to react. Psychologically, it describes a state of emotional paralysis. Whether the cause is negative shock or positive amazement, the core feeling is one of being frozen or speechless, where the mind cannot immediately process the intensity of the experience.
