There have been a few threads lately that have touched on signposts or stages of Enlightenment. Many will say that it is all indescribable, and ancient texts are open to vast differences of interpretation. While much of the path is beyond mind and words, at each “level” there are changes/things that everyone can understand. It is also not the same for everyone, but the following stages are a common progression. The following information is compiled from discussions with 4 self-declared “enlightened” individuals, 2 primordial (Dzogchen-like) masters and my own experience. Normal State – Wandering mind. Some will often have 3-6 (or more) threads/dialogs of thought jumping around.
Temporary One Thread – In meditation, one quiets to one focused thread (as in mantra or concentration). At this state, one may begin to notice energy (if looking for it).
Temporary quiet mind – One can begin to see/trace thoughts.
Stable quiet meditation – One can perceive the nature/energy of mind. Can perceive astral experiences.
Expansion of quiet mind to normal life – One begins to “see themselves” doing things. An example is seeing yourself getting angry, but can’t stop yourself.
Quiet mind in life – Usually only one thread going, sometimes no threads. Can see and stop yourself from getting angry.
Calm mind – No real thoughts unless there is something to do/decide. Meditation and life are the same. (McKenna books 1&2). Often described as nothingness. Many stop here and declare victory.
Noticing Oneness – Something “tickles” the calm mind. Curiosity returns. (McKenna book 3). Begin to break beyond the local body-mind.
See Oneness – Feels like every soul is inside you. Begin integration with existence.
Oneness – Can feel everyone and everything. Begin building rainbow/light body. At this level, a master can send mind-to-mind knowledge/transmissions and do lots of stuff.
Oneness beyond time – Can perceive parallel realities and beyond time.
Primordial State – Level of Prophets/Buddhas. Completion of rainbow/light body. Integration with God/Existence/Emptiness. Depending on your perspective, gone or do whatever you want.
  I hope you find this useful (or at least interesting ). Happy to discuss.   Enjoy the moment (and the week).
