Answer:
Personal unconsciousness.
Explanation:
Personal Unconscious is a concept used in Carl Jung's philosophy of empirical psychology. It applies to any memory that is present within the consciousness of a person, but not readily accessible for conscious recollection, i.e. memories that have been lost or hidden. Those may involve childhood memories that are lost or painful memories that the subconscious has removed from conscious memory. As per the question, Sam's feelings are restrained and therefore reflects personal unconsciousness.
