What does the idiom in your mean?

The idiom "in your" is not a complete idiom. It needs to be completed with a word or phrase to make sense. For example:

* In your face: This means to be bold, defiant, or confrontational.

* In your dreams: This means something is impossible or unlikely to happen.

* In your best interest: This means something is beneficial or advantageous for you.
