Is Luke really saying these words to Rey? If so, is it a flash back moment, or is it Force ghost Luke? Or is it just trailer marketing?

This phrase was said by Luke to Leia in The Last Jedi. In the old and abandonned rebel base on the mineral planet Crait, Luke and Leia have a very emotional reunion.
