Dreams involving seduction and deception can often reflect inner conflicts or feelings about trust and relationships in your waking life. The man in your dream may symbolize an aspect of yourself or someone you know, while the revelation of him being a devil or demon could represent fears or negative influences that you feel are trying to manipulate you.

The necklace with the word "Polygamorph" is intriguing. It seems to combine the idea of polyamory (multiple loves) and transformation (morph). This could suggest a struggle with your own desires for connection versus the fear of being overwhelmed or deceived in relationships. It might indicate a need to explore your feelings about loyalty, love, and the nature of your relationships.

Consider reflecting on your current relationships and any feelings of insecurity or trust issues you may have. This dream might be encouraging you to examine your boundaries and what you truly want from your connections with others. Think about what "Polygamorph" means to you personally and how it relates to your experiences with love and desire.
