For in that sleep of death what dreams may come.

I disagree with this definition; resurrected bodies, in the Christian usage of the word, with which Tolkien would be most familiar, are not the identical, original bodies but are a special kind, same in appearance, but differing in their material, perhaps? This accounts for the ability to disappear into the spiritual realm after resurrection.

This concept seems to me to apply to resurrected Elves and Gandalf (and, as a human exception, Beren); I tend to agree with those who consider the Barrow situation as something completely different: a kind of inhabitance, something like possession.
