A Dictionary of Dream Symbols

by Eric Ackroyd
(1) If in a dream you are seduced, it may be a reliving of an actual seduction, perhaps in childhood. Otherwise, it might express a desire for sex. In a man’s dream, a seductive woman / siren / mermaid may symbolize his anima in negative - destructive - form (see Brother / Sister). The latter may result from a negative relationship between the man’s mother and himself as a child. In any case, the dreamer would need to get in touch with his anima, enter into dialogue with her and take steps to rearrange his life to accommodate her just demands.

(2) If you are the seducer, the dream is probably a straightforward expression of sexual desire.
