For some people, sleep brings a peculiar kind of wakefulness. Not a dream, but a quiet awareness with no content. This lesser-known state of consciousness may hold clues to one of science’s biggest mysteries: what it means to be conscious.
The state of conscious sleep has been widely described for centuries by different Eastern contemplative traditions. For instance, the Indian philosophical school of the Advaita Vedanta, grounded in the interpretation of the Vedas – one of the oldest texts in Hinduism – understands deep sleep or “sushupti” as a state of “just awareness” in which we merely remain conscious.
Similar interpretations of deep sleep are made by the Dzogchen lineage in Indo-Tibetan Buddhism. According to their teachings, different meditative practices can be followed during wakefulness and sleep to acknowledge the “essence” of consciousness. One of those meditative practices is that of dream yoga or luminosity yoga, which enables the practitioner to recognise the states of dream and sleep. This aims to bring them to a state of “pure awareness”, a state of being awake inside sleep without thoughts, images or even a sense of self.
For western science, this state poses a conundrum. How can you be aware without being aware of something? If these reports are accurate, they challenge mainstream theories that treat consciousness as always about an object. For example, my awareness of the laptop in front of me, or the blue sky rising above my window, or my own breathing. The existence of this state pushes us to reconsider what consciousness is.
In those studies, we found a spectrum of experiences we called “objectless sleep experiences” – conscious states that appear to lack an object of awareness. In all cases, participants who alluded to an objectless sleep experience reported having had an episode during sleep that lacked sensory content and that merely involved a feeling of knowing that they were aware.

From a Buddhist POV, these states are samadhi or dhyana states, which are essential to successful Buddhist practice.
The reason these states are essential is they provide the experience of pure awareness, pure consciousness with zero self and zero referent.
The Mind-Only Buddhist explanation of these states is they are touching on or engaging with the universal Tathagata, or enlightened mind.
In modern philosophical terms, these states are awareness of ‘mind at large’ or some version of ‘quantum consciousness’ or the fundamental ‘field of consciousness or thought’, which is posited as a primary component of the cosmos.
These states are extremely valuable and worth remembering and pursuing.
In higher levels of samadhi, enormous joy or bliss is experienced along with a total absence of self or referent.
The highest samadhi state is perfect equanimity coupled with deep awareness of the Tathagata.
Samadhi states eventually bump up against nirvana.
I love Western civilization, but the one thing it deeply lacks is a tradition of knowing about and using samadhi, which at the very least provides a marvelous and wonderful place to stand aside from all that is mundane.
Philosophically, Buddhism recognizes ‘relative truth or reality’ (mundane reality) and ‘ultimate truth or reality’, the full knowing of which constitutes Buddhist enlightenment.
In many Buddhist traditions, samadhi states are understood to be natural and attainable by anyone who tries diligently.
If you are fortunate enough to experience samadhi without trying, be thankful!
You have gained a deep realization.
One of the most difficult parts of Buddhism for non-Buddhists to understand is the experience of samadhi.
Also fundamental to Buddhism is the experience of a clear conscience, an honest and pure mind which is gained through wholesome moral and ethical thoughts and behaviors. ABN
