Morphology

live + rent-free + in + someone's + head

The components 'live' and 'head' suggest an existence in someone's mind and 'in'/'someone's' mark possession, so a learner can infer something about occupying thoughts; however 'rent-free' is a metaphorical, culture-specific modifier (occupying mental space without cost) that many B1 learners will not know as a lexicalized unit. Because the overall meaning is inferable only partially through metaphor and cultural knowledge rather than strict compositional logic, it is not fully transparent but not wholly opaque either.

Etymology

Live rent-free in someone's head paints a picture of a person who lives in your house rent-free, taking up space without paying. So when something 'lives rent-free in your head' it 'takes up space in your mind' and you can't stop thinking about it.
