Transfixion refers to a state of being focused and engrossed in something. Its antonyms would include words that convey the opposite of this intense concentration. Examples of such words are "distraction," "diversion," "inattention," "neglect," and "indifference." They all connote a lack of interest or a lack of focus on a particular matter. Similarly, "disinterest," "disengagement," and "apathy" also convey apathy or disconnection from the subject at hand. Using antonyms of transfixion would help describe a situation where one's attention is dispersed and not entirely focused on a particular subject, leading to distraction or inattentiveness.
