Here are some possible interpretations and what they might mean in English:
* "Nuit et fais de beaux rêves": This translates to "Night and have beautiful dreams" which is a common French expression for wishing someone good night.
* "Nuit et fais-en de beaux": This could be translated as "Night and make beautiful ones" which would be a more literal translation. However, without context, it's unclear what "beautiful ones" refers to.
* "Fais de beaux rêves": This simply means "Have beautiful dreams" and is the most common way to say goodnight in French.
If you can provide more context, I might be able to offer a more accurate translation.
