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.
