When we read that God made Adam sleep in Genesis 2:21, the Rabbis tell us that sleep is a microcosm of death. It points to an end.
Perhaps Adam's waking revelation of another life made from him tells us that in waking from death, we will be joined with another. Complete.
And perhaps the waking tells us another thing: If Adam is like God, his own sleep/death tells us that God will die and rise to be united with his bride, too.
