I know for a fact that the word "unconfuse" doesn't exist, and I can't think of any phrase that mean "make your mind less confused", so what are some option. I am thinking of a situation where someone is saying a lot of nonsense and can't think rationally and someone tells him to "make his mind less confused" before saying anything that he may regret.

A few options are:
Get your head together or get your head on straight.
Also, pull it together.
They both basically mean "settle your thoughts/actions and behave appropriately."
