One of my professors teaches that the dichotomy of Man (mortal body, immortal soul) was not taught be the ancient Hebrews at all, but the hope of the Hebrew is resurrection rather than immortality of the soul. To the ancient Hebrew, a person ceased to be, in any real sense, at death, and is preserved only in the infinite mind of God until the resurrection. I would guess that since neither Enoch nor Elijah died physically, according to ancient Hebrew thought if my professor is correct, they live as Christ does, physically in heaven.
