What is when a girl says sweet dreams?

When a girl says "sweet dreams," it is usually an affectionate way to end a conversation or a text exchange. It can also be a way of expressing care and concern for the person's well-being and wishing them a good night's sleep. This phrase can be used by anyone, whether they are close friends, family members, or in a romantic relationship. It is a gentle way of showing someone that they are in your thoughts, even as they go to sleep.
