I have been years trying to find out what really happens with me when I sleep. However, not having come to any satisfactory revelation I am here asking if anyone has had any insight or direct experience on the nature of Deep Sleep. Why is Sleep even important?  Well, let's imagine that you live 80 years. From those, you will spend 27 years sleeping. Wow 27 years? Are you not curious what is really going on with sleep? On top of that, if you have awoken to consciousness, as your real nature and the nature of all that is, are you not puzzled about this unconscious sleeping mystery that takes out 1/3 of your human conventional life? In my investigation I have come across many possible explanations and techniques. I've researched about the Turiyatita state, said to include and transcend the three main states of consciousness that are waking, dreaming and deep sleep and is ever constant in all. I've studied about Cessation. It explains that consciousness and unconsciousness are codependentely arising one from another and in a cessation you are getting blinked out of both. However, none of these I have been able to awaken to so far, and seem to miss the point about something so commonplace as sleeping. I've also reflected on consciousness being an Infinite Scale and deep sleep just being a lower graduation, waking state higher and an Awakening much higher. While this explanation has logical sense to me, it lacks the firm clarity and unshakeability of Truth and remains in a superficial level. I've also experimented with Yoga Nidra and conscious sleeping successfully, yet so what? Even though I can have the experience, sleep has already happened in me and is still happening. In the case I experienced conscious sleep for the rest of nights of my life, I know that deep sleep has happened for years in a row for me. I've also realized that I imagined sleep and I had never ever slept in my whole life. This while having the solid rock of Truth does not correlate to all states of consciousness and clearly not in every day life. I don't find myself in a state to claim I have never slept in my everyday life, precisely because I sleep every night and I wouldn't if it was the case.  It also surprises me how little importance this topic is given, even Leo has rarely talked about it. Many here claim that all is consciousness: an Infinite Consciousness, yet every night they sleep and fall unconscious. That's like saying I am water and every night turning into fire. So then: If I am consciousness why do I sleep?
