If you are a man and you dream of mermaids and sirens, this may represent the image of a woman who you feel you could love, but who may also reject and destroy you. To dream that you follow her siren song suggests shallow will-power, or being easily misled by lust and base passion. So potent is this myth that the word siren is today used to describe a heartless, treacherous but irresistibly seductive woman. Alternatively, the mermaid may represent your anima, the feminine part of your personality, who, by leading you out to sea, is encouraging you to explore the depths of your own emotions.
Traditionally, the mermaid or merman belongs to the sea as well as the land and this symbolizes an ability to be deeply emotional and deeply practical at the same time.
In a woman’s dream, the mermaid is thought to represent a love rival. Finally, mermaids and mermen are feminine and masculine images of the link between your conscious self and darker forces you may not understand. Many stories tell of the difficulties of mating with a creature from the sea, showing how difficult it can be to unite the two sides of our nature. [1]
