The Conscious, Subconscious and the Unconscious Mind forms the three levels of the mind on which several studies have been conducted by the famous Austrian psychologist, Sigmund Freud.<br />These studies just have a theoretical basis as it is very difficult to prove these scientifically.<br />The three levels of the human mind can be very well studied by making use of the triangle analogy.<br />The tips of the triangle are compared to the conscious mind that occupies a very small portion of the space.<br />It is a reference to the fact that the conscious mind accounts for only 10% of the brain functioning.<br />Under this comes the section that occupies slightly larger space than the conscious mind.<br />The section comprises of the preconscious or in other words the subconscious mind which accounts for 50-60% of the brain functioning.<br />Below the section of the preconscious mind lies the section of the unconscious mind that fills up the remaining space up to the base of the triangle.<br />Thus, the unconscious mind accounts for 30-40% of the brain functioning.
