Lets go over all 9 hints of luke skywalker and his force projection technique in star wars the last jedi. During the last jedi ending scene the final fight...luke vs kylo ren! There are many hints during and before the battle that told us luke wasn't really on the planet crait and actually far away on the planet ahch-to. Director Rian Johnson placed clues here and there to tell us on a subliminal level on the first viewing. The last jedi ending scene is a very emotional one with lukes death happening just after using this technique.
