Morphology

lost + in + thought

The meaning is directly derivable from combining 'lost' (not mentally present/absent), 'in' (inside), and 'thought' (thinking), yielding the idea of being absorbed in one's thoughts. This figurative composition is common and mirrored in many languages, so a B1 learner who knows the constituent words will readily infer the intended meaning.

Etymology

Lost in thought comes from the image of a person who is lost, like on a path, inside their thoughts, so they do not notice what is around them. So, it means 'deeply absorbed' or 'unaware of surroundings'.
