Ok, so I'm new to this forum, I hope someone can help me

My boyfriend and I have been dating for almost 3 years now but in the past we've had some rough times where we weren't sure if we should stay together, take a break, or just break it off for good. Well in the past few months or so I've been having dreams of myself cheating on my boyfriend with other guys, none of them I know, they seem to be just random guys. I've looked at other dream interpretation sites and they say it could mean self-betrayal... I'm not really sure what that means...also, I've never cheated on my boyfriend before and I've just started having thoughts about it recently. Can anyone tell me what this could mean? Is it a sign that my boyfriend and I should take a serious break?
