The point I was trying to bring out is they can't tell us things because they are 'trapped' between the two places...they did not cross over!
I could accept that in some if-this-is-true-then-that-could-also-be-true sense.
But even then, these trapped souls could still offer insights that don't ever seem to be asked for. You meet someone that lives 500 miles from you and you tend to ask them what it's like where they live. Then you meet someone on entirely different plane of existence and you ask them all sorts of nonsense. It doesn't make sense to me.
The "trapped between worlds" bit bothers me, too. We're assuming they are dead people. Dead people were once live people, and live people are remarkably resilient. After a few years of being "trapped", dontcha think they'd just get on with whatever life they could live? I know that if I found myself trapped in a house for all eternity, I'd have to start doing SOMETHING. I surely wouldn't stand around screaming and regenerating images of how I died.
(Easy to say when I'm not actually dead, eh?)
