Unconscious Mind: This is a reservoir of feelings, thoughts, urges, and memories that are outside of our conscious awareness. It's like the hidden storage room in your house where all your forgotten items are kept.
Defense Mechanisms: These are psychological strategies used by the unconscious mind to manipulate or deny reality in order to protect oneself from feelings of anxiety or guilt. It's like your brain's own security system protecting you from emotional harm.
Id, Ego, Superego: These are three parts of the psychic apparatus defined in Freud's structural model of the psyche; they interact to form complex human behaviors. Imagine them as three drivers in one car (your mind), each with different goals - Id wants immediate gratification (like a child wanting candy), Ego tries to satisfy Id’s demands realistically considering social norms (like a parent negotiating with the child), while Superego upholds moral standards (like a strict teacher enforcing rules).
