Morphology

off + one's + dot

Although 'off' can signal abnormality, the element 'one's dot' uses 'dot' idiomatically (related to 'dotty' = slightly mad) rather than its literal sense, so the overall meaning 'not acting normally' cannot be predicted from the literal parts. This is a rare/dialectal idiom and the semantic link to 'mind/sanity' is not transparent or cross-linguistically obvious for a B1 learner.

Etymology

Off one's dot may come from the picture of a small dot or mark that stands for your mind. One popular story says that if your dot is 'off'—as if it has fallen away—you are not acting normally, so the phrase means 'behaving in a strange or slightly crazy way'.
