Violia,
I guess sometimes it could be the Self archetype, or the Freudian superego, or one of perhaps many other types of archetype,
http://en.wikipedia.org/wiki/Jungian_archetypes
Jung described archetypal events: birth, death, separation from parents, initiation, marriage, the union of opposites etc.; archetypal figures: great mother, father, child, devil, God, wise old man, wise old woman,Apollo, trickster, [18] hero - not to mention "Oedipus ... the first archetype Freud discovered" [19] or "number ... an archetype of order"; [20] and archetypal motifs: the Apocalypse, the Deluge, the Creation, etc. Although the number of archetypes is limitless, there are a few particularly notable, recurring archetypal images, "the chief among them being" (according to Jung) "the shadow, the Wise Old Man, the child(including the child hero), the mother ... and her counterpart, the maiden, and lastly the anima in man and the animus in woman". [21] Alternately he would speak of "the emergence of certain definite archetypes ... the shadow, the animal, the wise old man, the anima, the animus, the mother, the child". [22] Although five main archetypes were discussed in Jung's writing there are many others. The following are the five most common archetypes. [23]
