What is the subconscious mind ?

Unconscious is a set of mental processes that occur below the level of conscious awareness, as the conscious mind includes thoughts, feelings, perceptions, and memories, while the unconscious contains many complex processes that fall within the scope of decision-making and judgments that are processed outside the scope of awareness, in addition to intuition based on assumptions, accumulated experiences, and knowledge.
