A question has been bugging me for some time. Actually, make that a pair of questions, and there’s no clear answer in the movies (so far). I’d love to hear your thoughts on the matter.
At the end of Return of the Jedi, three dead Jedi pay Luke a visit (and say nothing). No one else pays them any mind, or even appears to notice. The only conversations Luke ever has with Obi-Wan after Star Wars are when he’s alone.
You would think that the ability to appear on the physical plane anywhere you wanted, any time*, Force Ghosts would make excellent teachers. They could pass on insights about the Force to the next generation. They haven’t.
* I have no idea how much ‘effort’ it takes to materialize as a Force Ghost. Being dead, they don’t have any resources to speak of.
There’s no proof a Force Ghost can visit someone who’s never met them while they were alive. There’s no proof they can’t, either.
I don’t know. What do you nerds think?
