How to Say Sweet Dreams in French

You're tucking your host family's daughter into bed, or sending one last text to a partner back in Lyon before you both drift off, and "Bonne nuit" suddenly feels too plain for the moment -- more like the sign-off on an email than something you'd whisper to someone falling asleep. You want the warmer version, the one that wishes them something nice while they're actually dreaming, and your brain reaches for a word-for-word translation of "sweet dreams" that doesn't quite exist in French the way you'd expect.

That's the real puzzle behind learning how to say sweet dreams in French: English has one fixed idiom and expects it to translate directly, but French instead builds the phrase out of ordinary words you already half-know -- beau (beautiful) or bien (well) -- and picks between a couple of options depending on how affectionate or casual the moment calls for. If you've already learned bonne nuit for saying goodnight, this is the natural next phrase to add: the one you say right as someone is about to close their eyes, not just when you're leaving the room.

Fais de Beaux Rêves: How to Say Sweet Dreams in French

Fais de beaux rêves is the phrase that actually matches "sweet dreams" in both meaning and spirit -- it comes from faire (to do/make) in its command form, plus de beaux rêves (some beautiful dreams). Said out loud to a child at bedtime or typed as the last line of a goodnight text, it carries exactly the same warmth English speakers reach for.

Key Phrases

• Fais de beaux rêves ! (fay duh boh rev) -- Sweet dreams! (tu, informal)
• Faites de beaux rêves ! (fet duh boh rev) -- Sweet dreams! (vous, formal or plural)
• un rêve (uhn rev) -- a dream
• beau / beaux (boh) -- beautiful (masculine singular / plural)

[AUDIO: Fais de beaux rêves] [AUDIO: Faites de beaux rêves]

Grammar Note

Faire is irregular in the imperative, and de beaux rêves hides a rule worth knowing on its own: when a plural adjective sits in front of a plural noun, des shrinks down to de.

• Common mistake: saying "des beaux rêves" instead of de beaux rêves -- the same shrink happens in de bons amis (good friends) and de belles vacances (nice holidays).
• Common mistake: conjugating faire like a regular -er verb and saying "faise" instead of the correct irregular tu form, fais.

Dors Bien: The Simpler, More Common Choice

Most of the time, French speakers actually reach for something plainer than beaux rêves -- dors bien (sleep well), built from dormir (to sleep). It's less poetic, but it's the phrase you'll hear far more often between friends, roommates, and colleagues signing off for the night, especially over text.

Key Phrases

• Dors bien ! (dor byan) -- Sleep well! (tu)
• Dormez bien ! (dor-may byan) -- Sleep well! (vous)
• dormir (dor-meer) -- to sleep
• bien (byan) -- well

[AUDIO: Dors bien] [AUDIO: Dormez bien]

Grammar Note

Dormir belongs to a small group of irregular -ir verbs -- along with partir and sortir -- that drop a consonant from the stem in the singular forms.

• je dors
• tu dors
• il/elle/on dort
• nous dormons
• vous dormez
• ils/elles dorment
• Common mistake: conjugating dormir like a regular -ir verb ("je dormis" for "I sleep") instead of using the correct irregular stem, dor-, for the singular forms.

Bonne Nuit, Dors Bien, or Fais de Beaux Rêves?

These three phrases aren't interchangeable, even though they all show up around bedtime. Bonne nuit (good night) is a farewell -- it's what you say when you're physically leaving someone or ending a conversation for the night, the same way English uses "good night" as a goodbye. Dors bien and fais de beaux rêves, on the other hand, are wishes for the sleep itself, said to someone who's about to actually close their eyes -- tucking a child in, or sending the very last message before you both put your phones down.

French parents lean on fais de beaux rêves constantly as part of the bedtime routine, and it's just as common as a closing line in a goodnight text between couples -- arguably more common there than "sweet dreams" is in spoken English, since French speakers type it more freely than they'd say it out loud to a coworker. Stacking phrases is completely normal too: "Bonne nuit, dors bien !" is an ordinary way to end an evening, not a redundant one.

Saying Goodnight Like a Local

Picture the last few minutes before everyone in a French household actually goes to sleep.

• Host parent, from the hallway: "Bonne nuit, les enfants !" (Good night, kids!)
• Child, already under the covers: "Bonne nuit ! Tu viens me faire un bisou ?" (Good night! Are you coming to give me a kiss?)
• Host parent, tucking her in: "Voilà. Dors bien, et fais de beaux rêves." (There you go. Sleep well, and sweet dreams.)

Now picture the same wish showing up somewhere just as common: a phone screen, right before two partners in different cities both fall asleep.

• Léa (11:47pm): "Je suis épuisée, je vais me coucher." (I'm exhausted, I'm going to bed.)
• Marc (11:48pm): "Fais de beaux rêves, à demain !" (Sweet dreams, see you tomorrow!)

Practice Exercises

• Fill in the blank: You're tucking a child into bed and want the warm version of "sweet dreams": "___ !"
• Fill in the blank: Complete the adjective shrink -- "___ beaux rêves" (des/de)
• Translate into French (vous, formal): "Sleep well!"
• Multiple choice: which phrase is a farewell, not a wish for the sleep itself? (a) Dors bien (b) Bonne nuit (c) Fais de beaux rêves
• True or false: dormir conjugates like a regular -ir verb.
• Translate into French (tu, informal): "Sweet dreams, see you tomorrow!"

Answer Key

• Fais de beaux rêves ! -- the warm, tu version for a child.
• de beaux rêves -- a plural adjective before a plural noun shrinks des to de.
• Dormez bien !
• (b) Bonne nuit -- it's a goodbye, while the other two wish for the sleep itself.
• False -- dormir is irregular, dropping the m in the singular stem (je dors, not je dormis).
• Fais de beaux rêves, à demain !

Sweet Dreams, However You Learned to Say Goodnight

• Fais de beaux rêves is the true equivalent of "sweet dreams," while dors bien is the simpler, more common everyday version.
• Bonne nuit says goodbye for the night; dors bien and fais de beaux rêves wish something for the sleep itself, and French speakers often stack all three together.
• The plural-adjective rule hiding inside de beaux rêves -- des shrinking to de -- shows up everywhere else in French, from de bons amis to de belles vacances.

Next time you're saying goodnight in French, out loud or over text, try reaching for fais de beaux rêves instead of defaulting to bonne nuit every time. Head over to Passage's Vocabulary section for more everyday phrases like these, or leave a comment with how you use it tonight.
