My bf dreamt I was cheating on him with him

I usually interpret my own dreams & some of boyfriends when he tells me about them. But this one has got me beat, I just don't understand it. My partner woke me up this morning & told me this dream:

We were in a bedroom (a strange place) talking & I left saying I'll be back. He said I was talking to another man outside the room & I was getting flirty. He peered through the glass to try & see who I was talking to, but couldn't see through it. He had a feeling I was kissing this person so stepped out the room & saw that I was kissing someone else, but it was him. He watched me kissing him then woke up. He said it left him feeling strange & unsure & left the house in a weird mood.

It's not uncommon for us to dream of each other cheating after a big argument. But this seems different somehow. Things in our relationship have changed & im wondering better or worse...

Anyone have any ideas?

I don't attach much meaning to dreams with interpretations

but here is a parody 'not awake' of both lucid dreaming and Katy Perry (Wide Awake)

it references partner cheating towards the middle and the end

but it references dozens of common dream themes

I think it shows that everyone has plenty of common dream types, I wouldn't attach any meaning to it

the more to think about it, or attach meaning to it, the more expectation will cause you to dream of such things

and if you don't have much dream recall, highly emotional dreams will be plentiful among the ones you do remember
