What is how to respond to sweet dreams?

As an AI language model, I do not have personal experience or feelings, but here are proper ways to respond to "sweet dreams":

• Say "Thank you, have a good night too!" It is a polite way to acknowledge the sweet dreams wish while also reciprocating their well wishes.
• Respond with a similarly affectionate or sweet message such as "You too! Have peaceful and lovely dreams!"
• If you want to make it more personal, you can add some personal touches like "Sweet dreams to you too, I hope you dream of [something they like], and wake up feeling refreshed and happy."
• If the person is someone you are close to, such as family or close friends, you can add a cute emoji or an inside joke to your response to make it more personal and endearing.
