Freud divided the mind into its conscious and unconscious states. The conscious mind contains all the thoughts, feelings, cognitions, and memories we acknowledge, while the unconscious consists of deeper mental processes that are not readily available to the conscious mind. However, the unconscious is where much of the mind’s work gets done; it's the repository of automatic skills, the source of stored and often repressed memories of traumatic experiences, intuition, fantasy and dreams, and an engine of information processing.
While it is difficult to measure what exists in the unconscious, we know that even fleeting perceptions can leave lasting imprints on the unconscious mind long before you become aware of them. What lives in the unconscious mind can also eek out at any time, in different ways, from misspoken comments to random behaviors. From these unconscious “leaks” you may gain a clearer understanding of your inner state and deeper motivations.
