The findings of the research by the mental phenomenologist Robert Monroe.

The term phasing is a metaphor derived from physics, which conceptualizes consciousness as a waveform that can either be aligned or non-aligned with physical reality. For example, when we are 100% phased into the physical we are considered perfectly aligned with normal physical input and waking reality. In Monroe speak, this is called C-1 consciousness or primary phasing. As consciousness moves further away from the physical (and the senses) consciousness is said to phase into other ‘focus levels’. The first of these is [F]ocus 10 - the state of mind awake/body asleep.
The first set of these focus levels (and the focus levels the Gateway Experience pertain to), can be said to a extent maintain varying degrees of relationship to the physical in that they usually do not automatically include being fully present at a certain “astral location”, but rather, involve an expanded state of awareness of some kind while still remaining in the same “location”. These focus levels have been described as follows (Monroe, 1994, p. 248):
[Focus 3: State of increased mental coherency and balance]
“Focus 10: Mind Awake/Body Asleep
Focus 12: A state of expanded awareness
Focus 15: State of no time
Focus 21: The edge of time/space where it is possible to contact other energy systems.”
“It is important to realize these focus levels are merely arbitrary numbers and signposts to identify the state of consciousness one is in. In case you’re wondering, there is no Focus 14 or Focus 16. However, beyond Focus 21, several other focus levels have been identified further removed from the physical …,” and which involve among other systems the perception of belief system territories (‘astral planes’). Thus, The Gateway Experience is meant as a platform from which to explore further on your own." [end quoted text from FOCUS 10: Mind Awake/Body Asleep by Ashes]
There is some confusion and uncertainty regarding the Focus 12 through 21 states and differentiating them appropriately. Several practiced “phasers” have noted how the transition from Focus 10 to 12 is often characterized by seeing several abstract forms and colors, often very quickly followed by a 3-D effect in the blackness surrounding you. Hence, there is some controversy on the exact delineation between Focus 12, 15 and 21. Perhaps the 3-D blackness of Focus 21 can be said to be more expansive to the extent that it starts to touch upon ‘astral locations’ beyond Focus 21.
This brings us to phenomena in Focus 21, which is the ideal platform for further experiences in the other Focus levels. The following quote will serve nicely to illustrate the transition into 12 up until 21, and how to reach the "higher

However, staying with the ‘traditional view’ the following focus levels can be identified as follows on the basis of Monroe’s and Bruce Moen’s work (From Bruce Moen, Afterlife Knowledge Website).
Focus 22: Within Focus 22 we often find those perhaps still physically alive who are in an unconscious state. These include people in comas, in drug induced states, who are dreaming, who are insane or deranged. This is a very chaotic level.
Focus 23: In Focus 23, the human inhabitants tend to be those no longer physically alive who have become “stuck” for one reason or another. Often they are confused about or unaware of their death. Many here attempt to maintain contact with the physical world around familiar people or places. These are the ones we call ghosts. Focus 23 inhabitants are stuck because they are unable to leave through their own resources. The range of their free-will choices is extremely narrow. They are typically alone and completely isolated from communication with other humans. This can occur through the circumstances of their death or habitual patterns of thinking prior to death.
Focus 24,25,26: Inhabitants of The Belief System Territories are attracted to specific locations by Afterlife beliefs they held while physically alive. Every set of Afterlife beliefs held by humans at any time has a specific location with these Focus levels. In a sense, Belief System Territory inhabitants are stuck like those in Focus 23. The difference is that they are not isolated from contact with others. All inhabitants of a specific Territory are in contact with all others sharing their beliefs. Contact with anyone holding conflicting beliefs is severely limited. Free will choices here are restricted to only those compatible with the prevailing beliefs. Some of these areas look like Heavens, some look like Hells. Each one is rigidly structured around the beliefs held by the inhabitants. In my experience, it is extremely difficult to move people from this area to areas of greater free will choice.
Focus 27: Focus 27 is the Afterlife area of greatest free will choice for its inhabitants. It’s an area created by humans and often resembles physical earth environments. Contact and communication is open between all inhabitants. Many people living in Focus 27 provide assistance to new arrivals in their adjustment to living in the Afterlife. It is a highly organized and structured area. There are Centers of activity here providing for the needs of human beings in their continuing development in the Afterlife. In my explorations, I’ve found Centers for: Education, Life Review, Health and Rejuvenation, Planning, Scheduling, Rehabilitation, Humor, and many others. These Centers also coordinate activities in the physical world to assist in human development.
Lastly, there is beyond focus 27, which is outside of the realm of human consciousness as we know it.
