Various studies of the human mind and behaviour have revealed that unlike all other animals consciousness of human beings exists in three levels. Experts have identified these levels on the basis of having different effects on the overall identity of any individual. These levels are termed conscious, subconscious, and Unconscious. As the name suggests the experiences that we perceive immediately are through at the conscious level of the brain. Anything that we try to understand, remember or recall is also a function of the conscious mind. But there are also some memories that we cannot recall easily but do affect our conscious decisions that are said to be under the purview of the subconscious mind. And finally, there is always some deep awareness and instinct that controls our body without even our decision. This deep level of consciousness is represented by the unconscious mind.
