The term "pre occupying" implies taking up space in one's mind or attention, whether consciously or unconsciously. There are several synonyms that can be used to describe this state, including "distracting," "engrossing," "absorbing," "captivating," "fascinating," "preoccupying," "consuming," "prepossessing," "enchanting," "enthralling," and "immersive." Depending on the context, one or more of these terms can be used effectively to convey the sense of being preoccupied with something. The key is to choose the word that best fits the situation and conveys the desired nuance, whether that be positive, negative, or neutral.
