Understanding the Unconscious
The unconscious is where most of the work of the mind gets done; it's the repository of automatic skills, the source of intuition and dreams, and an engine of information processing. Fleeting perceptions may register in the unconscious mind long before are aware of them.
The unconscious mind is not some black hole of unacceptable impulses waiting to trip you up, but it can be the source of hidden beliefs, fears, and attitudes that interfere with everyday life. Most forms of psychotherapy aim to bring into conscious awareness many of these hidden hindrances, so that we can examine them and choose how to deal with them.
