It strikes me that dreaming sleep (of the usual, broadly nightmarish or bewildering kind) is often like the 'underworld' death as envisaged by the Ancient Greeks (Hades) and Ancient Hebrews (Sheol) - that is a 'demented', passive state of very partial awareness - with perplexity as the dominant emotion.
In sleep; life happens-to-us and we strive, and fail, to make sense of it, and to cope with it. Our minds are porous and connected with the dream environment - we are like the 'gibbering ghosts' of the underworld.
In dreams the environment affects our mind - and our mind affects the environment in a reciprocal causality. We are acted-upon rather than acting: there is no freedom in a dream...
The gift of Jesus is to be born-again, to waken from this unending nightmare - awaken to resurrected eternal life - that is by incarnation to be separate from the environment and act to act in free agency from it; to be alert and conscious and creative in relation to the environment rather than swept-along passively, uncomprehendingly, in perpetual bewilderment.
Dreaming sleep is a temporary death - although modern Man assumes that death is a non-being much like deep sleep: unconsciousness and oblivion, rather than the underworld, nightmare state of dreaming sleep. But by dreaming sleep, of the nightmarish/ bizarre/ confusing/ helpless kind... we can know what it is we are being rescued-from.
Jesus came to rescue Man from the inevitability of the underworld nightmare of death - by resurrection; and with the offer of a gift of life eternal, which is a creative state of divine being.
(But death is necessary: to be reborn we must die; and death is bitter vinegar, as well as purifying hyssop.)
