How it's used
Use this phrase to question someone's sudden lapse in judgment or bizarre behavior. It implies that the person is acting so strangely that it seems as if an external, supernatural force has taken control of their senses. It is a very common, lighthearted way to tease friends or family when they make a foolish mistake or act out of character.
Examples
Why did you suddenly buy so much stuff, have you lost your mind?
He is acting like he is possessed, his speech is completely incoherent.

Common mistake
Do not use this to describe actual mental health conditions or serious medical issues, as it is strictly a colloquial idiom for temporary lapses in judgment or strange behavior. Using it in a clinical or serious context would be highly inappropriate and offensive.
