Hi @cabernet! Seeing the dream in full detail would allow me to give you the most guidance but these are dreams that are trying to get you to examine your feelings in the relationship. For example, the back rub one is saying that something in YOUR past (back) rubbed YOU the wrong way (to use this dreams pun) and you are now projecting stories from those experiences onto your current relationship (SO giving the rub). These experiences could be abandonment or betrayal experienced in other relationships and this even usually has far less obvious roots in childhood from when we first felt abandoned by a parent. I use these examples to give you food for thought, without seeing your dream I can't give you much more than general examples.
Sleeping with someone who isn't our current partner in a dream is fine to do because it's representing us getting intimately in touch with some aspect of our selves. Confidence and self esteem if it's a man; Emotional expression, compassion and intuition if it's a female.
If you were cheating on your SO with the intent to cheat like "ha this is what you get" then I'd really need to see the whole dream to give you a real interpretation.
From what you've said however, I can tell you that this dream is working to get you explore more of the buried feelings you have in this relationship which may not have so much to do with your SO as much as it has to do with how you've been hurt in the past.
Wow. This is excellent. Thank you for taking the time to answer this with the minimal information I gave you. I wish I remembered more of it.
Without getting into details, this was eerily accurate... You know, I always thought this whole dream interpretation thing was similar to something like palm reading but you've definitely changed my view on this with the little interaction we've had. I'm super glad I found your page! Looking forward to learning from you :)
I'm happy to hear that! It's for sure the real deal. ;) Looking forward to helping with more dreams. :)
