When we settle into bed, we all enjoy at least 2 states of consciousness: sleeping and dreaming. If we have a history of samadhi (yoga) in meditation, that creeps into our sleep time too, with various periods of transcendence (turiya) in sleep. This is especially true after the witness is established and there is a value of awakeness 24/7.
Part of our night is spent in the mind and emotional bodies, processing the day’s and life’s experiences. This shows up as dreams, in many combinations.
In deep sleep, we settle into the bliss body and are deeply soothed. However, this detail is often masked by the fog and noise of unresolved experiences.
The rest we get in sleep is not deep enough to process the deeper traumas so some of it tends to build over time. And if we’re experiencing major or constant stress, sleep will not be enough to process it all.
With the witness and awakening, this processing becomes more conscious, although there shouldn’t be an expectation of constant awakeness in sleep. While hyper-alertness can arise, it usually settles out into a simple continuity. As the mind and senses go off-line in deep sleep, awareness settles from experiencing into a simple continuity of being.
As the burden of our past is resolved and the clarity and depth of the awakening deepen, sleep becomes deeply enjoyable. We might compare it to a lovely deep meditation. Yet the style of experience is different. In sleep, we’re dipping into bliss within the state itself.
