I recommend the best sentence for sleeping as follows:

1. I hope you have sweet dreams tonight, good night.

2. Close your eyes and let your thoughts drift away in the wind. Good night.

3. May you be surrounded by gentleness and sleep peacefully. Good night.

4. Put down the fatigue of the day and go to sleep with a smile. Good night.

5. Let the quiet night soothe your uneasiness, good night.

6. May the stars illuminate your sweet dreams, good night.

7. May your dreams be filled with happiness and warmth. Good night.

8. Quiet night, I wish you have a beautiful dream, good night.

9. Let the beauty sleep with you tonight, good night.

10. Good night, may the moonlight protect every dream you have.
