If a human life and its egotistic development encounters the "king of terrors" as terminus, then at that level of awareness, there is "no thing" post-passing. However, the arc of a normal or typical life resembles a "day in the life" inasmuch as the dawn's morning light brings hope, freshness, and, as the soul-field progresses through its day/life, it learns some useful behavior. Toward the end of the day/life, if the soul-field has had a "good day," passng into sleep/post-passing is sweet, peaceful, restful, and hopeful as to what dreams/heaven worlds may come.
If the soul-field reflects a prior incarnation of staying up past its rest-time, abusing substance, etc., there may be a waking to grouchiness, etc. If the soul-field enjoys a quiet prayer or Scripture verse or other words of wisdom in the morning, it resonates with that wise dominion, with that heavenly Love, and has strength throughout its day.
If the soul-field, at the end of its day/life, is suffering bodily wear-out, or worse, if the soul-field is not able to make systematic sense/philosophize about its experiences, then sleep/passing on may seeming meaningless. At that level of awareness, yes, there is a period of "nothing after," until the soul-field's day's/life's dross is skimmed off by what dreams may come. At some point in the soul-field's returning arc to less-surly, less-earthly bonds of higher light, the soul has a road to Damascus experience, in which it realizes it is, post-passing, alive. At that juncture, Angels and Saints are able to minister more directly to the soul, much as lucidity in dreaming is a function of integrated personality.
At that juncture, the "what was the embodiment for" is answered as the soul becomes more attuned to what acts and thoughts and feelings import, in the heavenly calculus of divine Love, Light, and Wisdom. Such feelings are self-realization and become part of the soul's treasures in heaven, of its real Self.
