rent-free
/ˈrɛnt friː/
Very CommonSaid of a thought, person, or thing that keeps coming back into your mind without you wanting it to.
Almost always about something you don't want to be thinking about. Using it for positive obsessions is less common but not wrong. The comedy is in the powerlessness.
