Another thing worth mentioning about the whole “sensed the death of her son” thingy is that the film is built around it. Leia’s body doesn’t vanish until Ben’s does because that’s when she’s completed her “Jedi path”. Yes, it may be stupid, but it’s just the way they made the film.
The thing is the film isn’t built around it, it comes out of left field at the eleventh hour, there’s no build up before it and the “payoff” works fine without it. Implying Leia waited for Ben and maybe guided him across works on its own without any random fulfilled prophecy, same with Ben choosing to give his life force to Rey. If anything it robs agency from the characters to imply this is how it was all set to happen.
Prophecies and visions in Star Wars are never this hard set in stone, always in motion is the future, to imply Leia “sensed” how everything would happen some 20 years before is pretty ridiculous, not to mention nothing we see from Leia in VII VIII or IX implied she had such knowledge. Personally I hope “sensed the end of her Jedi path” can be polished to an acceptable degree, that seems to me like it would make the most sense.
