Morphology

like + a + dormouse

The meaning 'sleeping very deeply' is directly derivable from the simile structure 'like' + 'dormouse' because a dormouse is known for long, deep hibernation; a B1 learner who knows both constituents can infer the comparison. This animal-simile pattern is cross-linguistically common and follows straightforward compositional logic, so the expression is transparent to learners who know the words.

Etymology

Like a dormouse comes from the small animal called a dormouse, which sleeps through the winter and looks very still. Because the dormouse sleeps so deeply, saying someone sleeps like a dormouse means 'sleeping very deeply or soundly'.
