According to Mircea Eliade, nymphs correspond in essence to running water, fountains, springs, torrents and waterfalls. The best known of the nymphs are the sisters of Thetis, the Nereides, who figure in the expedition of the Argonauts. By virtue of their association with the Element of water, their significance is ambivalent and they may preside equally over birth and fertility or dissolution and death.
Jung, from the psychological standpoint of his theory of individuation, regards the nymph as an independent and fragmentary expression of the feminine character of the unconscious.
A dream of a nymph predicts an interesting romantic experience.
