Detailed explanation-1: -According to Freud (1915), the unconscious mind is the primary source of human behavior. Like an iceberg, the most important part of the mind is the part you cannot see. Our feelings, motives and decisions are actually powerfully influenced by our past experiences, and stored in the unconscious.

Detailed explanation-2: -In psychology, the human psyche refers to all the parts of the human mind that affect personality. According to Sigmund Freud, the psyche consists of the id, the ego, and the superego, and it functions at different levels: the conscious, preconscious, and subconscious.

Detailed explanation-3: -Freud gave consciousness the quality and capacity to transform experienced activity into unconscious states, similar to how different forms of energy are interchanged in physics. It could also play a part in inhibiting and restricting certain thoughts from becoming conscious.

Detailed explanation-4: -The ego is the only part of the conscious personality. It’s what the person is aware of when they think about themselves, and is what they usually try to project toward others. The ego develops to mediate between the unrealistic id and the external real world. It is the decision-making component of personality.

Detailed explanation-5: -In psychology, the psyche /ˈsaɪki/ is the totality of the human mind, conscious and unconscious. Many thinkers, including Carl Jung, also include in this definition the overlap and tension between the personal and the collective elements in man. Psychology is the scientific or objective study of the psyche.
