You're tired of your boyfriend and no longer interested in him. Immediately move on.
What does this terrifying dream mean? I had a dream about fighting an evil man and almost killing him, until I suddenly realized that this man was my boyfriend.
Sounds like the plot to the movie Scream. All along her boyfriend was the killer. But if it makes you feel better it was just a dream.
Dreams are not always particularly meaningful. Sometimes they are just the subconscious cleaning your mental "house."
I think it's probably an indication that you have some mixed feelings about your boyfriend.
(If that makes, sense to you, use it; if it doesn't, irnore it.)
You may be in a toxic relationship.
Wow, so many amateur psychologist dream interpretations. I have no idea whether they are right.
But, I suspect it means nothing.
