The phrase "unconscious level" refers to the depth of an individual's subconscious mind. It is a state of awareness that occurs below the level of consciousness, where thoughts and feelings are processed without the individual's full awareness or control. This level of consciousness includes automatic behaviors, such as breathing and heartbeat, which are not actively controlled by the individual. It also includes repressed memories, emotions, and beliefs that may influence an individual's behavior without their full understanding or consent.
