Boyfriend Problems (Cheating)

So my boyfriend and I have been having some problems recently. Honestly, they’re just smallish fights where we just piss each other off. But- the other day I had a dream where I was kissing one of his friends and I just had the same dream right now with a different friend. I have never cheated on him / will never cheat but I’m really confused as to why I’m having these dreams. I’m not even close to those friends, and although they’re good looking men, I’m not attracted to them or anything. What I’m asking is- is this a sign or is it just a random thing? And should I feel bad about it? I’m absolutely not going to tell him because it’s just a dream, but I feel horrible that it’s happening and wake up feeling like shit. They’re super quick dreams and usually something else is happening in the dream too, like the kissing is not the main focus. Could someone let me know if they think this is correlated to our fights or if it’s just an unhappy coincidence? Also- at the moment we are good and are not fighting anymore
