A symbolic figure incarnated by the mermaid. The myth of sirens is one of the oldest, as already in ancient Greece there existed stories about them. They represent the feminine side of the mind and evidence the mystery that surrounds the human psyche. Sirens bring secret wisdom from the depths of the subconscious (the sea). If a man has this dream, he may be afraid of his femininity or of his dark thoughts. For a woman it manifest the doubts about the nature of her own sex. Further, thanks to the seduction that a siren’s song exercises over masculine energy, it represent the temptations or passionate desires. Dreaming of the siren’s song foretells possible deceit in love. Mythology offers many figures that are part human, part animal. The major part includes the conscious mind; the minor part, the primitivism and irrationality that the conscience needs. Originally, these symbols were conceived to demonstrate that human nature and animals are inseparable.
