http://www.afterlife-knowledge.com/ret-arch/here are some descriptions on this site which may help you grasp the concept. essentially, on occassion, not in most cases, there are some folk who transition into the afterlife and are needing to be escorted, or awakened that they have actually made their transition. they may be in shock if it was a truamatic ending.
C1= Consciousness level one...our waking state of mind, everyday state of mind
focus 27 a level of the afterlife; a place we give a name to enable us to focus, or bring those who have been retrieved..everything is there, like hospitals, schools, everything is there that is found here. I welcome better descriptions. this is just brief.
