I could see how that disturbed you. But still, I don’t think it means anything…unless you think it does.
I’ve had very disturbing dreams in which I bludgeoned my brother to death with a knife–but I seemingly had no choice. The thing is, I have no ill will towards my brother, none in the least. There’s absolutely nothing subconscious that could have prompted this dream. Nothing. And I woke up feeling horrible for dreaming it. Where did it come from? To this day, I can’t fathom an explanation. Sometimes our minds do funny things.
But in the end, it’s you who knows how to interpret this dream. If I had a dream like that, I would simply think that’s the id taking over and playing out a fantasy. I believe every single one of us is capable of infidelity given the right circumstances. And in our dreams, the id plays out a scenario we might not ever consider in real life. So what? Unless you’re worried that you might actually do something like this in real life, I wouldn’t sweat it.
I would only worry if you didn’t feel disturbed at all when you woke up. Yup, I’ve had those kind of dreams too - luckily, so does my SO, and we like to share “How weird was YOUR night?” stories when we wake up.
For the record, for about the first 10 years we were together I would occasionally wake up and be very confused… who am I in bed with? Am I supposed to be? What is our relationship? Glad that part seems to be waning at 17 years…
Unless you’re one of those relatively rare people who dream lucidly, you have no control over your actions in your dreams, even if dreaming you knows it’s not the right thing to do. If you had control over it, you wouldn’t have dreamed you decided to cheat since you don’t seem like the type who’d stray in real life. In control of your dream, dream-self would have turned her down.
We all do things we wouldn’t in real life in our dreams. Not too long ago I dreamed that I helped a very former teacher - I haven’t seen him in a decade- cheat on his wife (yes, I knew he was married in the dream). There’s no way in hell I’d do that in real life. I’m not that type of person, and we won’t even get into the fact that he’s old enough to be my dad and looked a lot like Dean Koontz’s old bookjacket photos…
