The subconscious is a collection of all our thoughts, memories, and emotions that we have accumulated over a lifetime that we are not aware of. While we observe consciousness on only one level, the one that is real to us at a given moment, either in waking or in a dream, we observe the subconscious on nine levels. Levels that are close to the conscious state are also the shallowest. This is where the alpha state of sleep enters when we know what we are dreaming. In sleep we still have beta, delta and theta states. In delta waves we sleep the deepest, the body is the most relaxed and we do not remember sleep. Given that the subconscious works on all nine levels, those that are closest to the conscious state, and are both the most accessible to study and are closest to the current incarnation. The deepest is the ninth level that only mystics can reach, persons who are deeply connected with truth and with God.
