Thanks Webgoji for this explanation, as it is a difficult topic to define.

Years of mindfulness trains the conscious mind and opens to what our subconscious mind holds (this is where awareness comes in) key of understanding how to incorparate the mental activity not directly perceived by the consciousness, from which memories, feelings, or thoughts can influence behavior without realization of it. While meditating these aspects become clearer.

Awareness of the gross and subtle mental phenomena in the mind while we are awake, or at sleep, or during meditation.

Lucid dreaming is a form of OOBe because it takes place in a different dimension/level of reality.

Astro projection is unique and I can not say what it is or is not.
