i imagine that without muscles and things, a skeleton would be shorter in death. Not a doctor, just speculating.
Not a doctor either but in terms of height it doesn't make sense if the difference is too great. Only fleshy areas that would affect height are the top of your craniun, where there's only skin and a little flesh, and the bottom of your feet which is a bit meatier, but not much.
But in Tribunal expansion for Morrowind there were dwermer ghosts. How come they stayed on this plane?
I think it was only the living Dwemer who got to go wherever the Dwemer went.
