What is the unconscious mind?
Each individual has a conscious (what we are aware of) and unconscious (what we are unaware of) part of the mind. Sigmund Freud once described the mind using the metaphor of an iceberg. When you look at an iceberg you'll see the top of it above water which can be quite big, but when you look underneath deep down into the ocean you'll see a larger amount of the iceberg. What's interesting is the vast majority of the iceberg is actually underneath and invisible. Freud uses the iceberg metaphor to describe the conscious mind and the unconscious mind. The conscious mind is the visible portion and the unconscious mind is the portion not visible above water. The unconscious mind controls a lot of what we think and how we behave. And we're simply unaware of it.
