The condition in which mental processes occur and outside objects and events are perceived with the mind nearly or totally unconscious of them. Such subconscious impressions or events may be forgotten at the time but may nevertheless exert a continued influence over the conscious mind, or may at a subsequent time come fully into consciousness. Much importance is attached to the influence of painful or unpleasant experiences which, although forgotten, continue to influence the mind; these may be a factor in the development of anxiety states. This injurious influence may be reduced when the subconscious impressions come fully into consciousness and are then remembered and clearly seen in their relative importance.
