It means "I return" in French. I learned that term from Daphne DuMaurier's book, Rebecca. Perhaps you have heard of the movie Laurence Olivier starred in of the same title, it is adapted from this book. It is an interesting book, reminiscent of Bronte's Jane Eyre.
A very dear friend of mine has returned after a week's absence. It is beyond wonderful to know she has returned. Without her, I have felt lost, deeply anxious, and deeply sad.
I know that no one will always be around in the live realm, but it just feels so joyous when you can talk to them when they are. They are never really gone, but memories always are a bit weaker than how they were in life.
Someday we all accept what is inevitable. For now though, I will revel in the live realm with this dear friend. It is precious beyond the concept of precious that we all learn as children and remember all through adulthood.
