DreamsMaster: This dream could mean different things, based on what’s going on for you personally in your life right now.
For example, if in your waking world you have a strong physical attraction to your friend’s wife, then the dream may be providing you with a safe and socially acceptable outlet for that urge.
If you do not have a strong attraction to her physically, are there other aspects about her that you admire? In this case, joining with her intimately in the dream could symbolize a desire to join more closely with those aspects of yourself.
If in your waking world you don’t like this woman at all, then the dream may be suggesting you look more closely at the reasons why. What you don’t like about her may be some shadow side of yourself that you need to come to better terms with.
If you have neither positive nor negative feelings toward this woman, the fact that she’s your friend’s wife could actually represent a desire to have a closer relationship with this friend, not necessarily physically but in some other way that increases the bond between you.
As you read through these possibilities, did one strike you as more fitting than the rest? If not, to add further clarity, think about what occurred the day or night before the dream, and see if you can connect any of those thoughts and feelings with the feelings that you experienced in the dream.
