Bro I would have the same kind of dreams about my partner. I would wake up real annoyed at her and hold a grudge for ages lol. But this was when we first met and for about 2 years I would dream that she was cheating on me in front of my face. I think what helped me was once I began to trust her 100% these dreams stopped. I have now been with my partner for 9 years and I trust her completely and have not had a dream of this sort for 7 years. I hope I dont have a dream like this ever they really are one of the worst form of dreams there are
