The Void in the NDE context is a condition or "realm" of one's own making constructed only of the thoughts and mental constructions along with the emotional baggage available to those persons. Various case histories point to a state that is generally to be avoided, since a world only of one's fantasies can turn out to be a Hellish prison. ... Otoh, in certain Sci-Fi stories, people can supposedly be trapped in a type of Void that is "apparently" Happy, while the inhabitants believe they are in a "real" Heaven. This of course leads us to an interesting philosophical conundrum; but the Void in the article below appears to be an isolationist world not characterized by the happiness that Vicki experienced in her meeting with Jesus and the dead people (Cf. previous NDE post).
