'Sleep well' is a common sentence that is used in the English language, usually said as an informal phrase between people who are close to one another. 'Sleep well' can also hold other contexts, and might still confuse even native English speakers. This post unpacks the meaning, correct, and incorrect use of the phrase.
Meaning
The phrase 'sleep well' is a common saying that is mostly used in the English language.
Unlike most sayings, the phrase 'sleep well' actually implies that the speaker wishes a good night (and thus, sleep and rest) for the person who they are saying it to.
'Sleep well' can be said to someone as a statement, as a question, or might be said as a response to someone.
The phrase can be said on its own, or it might be nested in a sentence.
The phrase tells someone to sleep well (as a desired wish for the person that it is being said to), or implies that someone has 'slept well' in the past tense.
When someone 'did not sleep well' the phrase implies the opposite as a statement, or says that someone had a restless sleep or night instead of a good one.
There are many other ways to tell someone to 'sleep well', including to use the common phrase 'sleep tight' to say the same.
The phrase 'sleep well' is usually kept for close connections, and it would be considered inappropriate or too informal in a professional context.
If the phrase 'sleep well' is used out of context (or said by an undesired person), it can become more than inappropriate (and might even be seen in horror movies or thrillers).
'Sleep well' can also be used with humor or irony, anywhere someone is not supposed to be asleep (for example, someone who has been knocked out or eliminated from a fight).
Example Usage
“I don't know if I should send you another message after the three hundred of them I already have, but decided I was going to anyway. Sleep well and have a great day tomorrow.”

The phrase 'sleep well' is so common that it could have simply become part of common speech and dictionaries so fast that nobody noticed.

'Sleep well' has become common enough that the origin can only be traced back for sure to the beginnings of the use for the word 'sleep'.
Sometimes the phrase is said as 'sleep tight', although this saying is a reference to a longer saying that can also imply 'don't let the bed bugs bite' as a rhyme that has been in use for at least several different centuries.
