What if sleep is practice for death? All of our lives, every single day we go to sleep and most times we dream. Could it be that the sole purpose of sleep is to practice dreaming in preparation for the “Big nap”. Sure our body goes through some physically restorative processes as we sleep, but in a metaphysical sense every dream could be an opportunity to create our own reality, or non-reality; what is reality?
I totally agree with you; I’ve heard many meditation practitioners are able to maintain an unbiased, reflexive consciousness throughout dream, and deep sleep states. (This is considering that our whole lives are spent moving through three states: waking, dreaming, deep sleep). If death is the beginning of another stage of dreaming (which many consider life to be) could it not therefor be deep sleep? And thus, Tibetan Book of the Dead- a.k.a. consciousness persists through the death of the body, if it recognizes its own true immortality. I’ve just recently started meditating twice daily, and can practically lucid dream every night (with the help of a dream journal) and am already noticing dramatic shifts between states of consciousness throughout the daily cycle.
