So, I was marathoning all 9 Star Wars movies again because.... well, why wouldn't I right?
I came across something I never thought of before.
The force ghosts that we see in the movies only appear to those who knew them in real life, and never appear to those who didn't.
Obi-wan is told that he would be able to communicate to Qui-gon, but Qui-gon never appeared to Luke or Rey.
Obi-wan and Yoda both appear to Luke, but they didn't appear to Rey. Even when Yoda talks to Luke (Last Jedi) he doesn't talk to Rey.
Anakin appears to Luke at the end of RotJ, but he never appears to Rey.
Luke and Leia are the only ones who appear to Rey - they are also the only two she's met.
Are Force Ghosts only able to appear to those who interacted with them in real life? Is there anything to back this up, or to disprove it?
If not, it just seems that the whole Jedi Council could have gathered with Rey and discussed how to defeat grandpa.
