Is it weird I feel like I cheated on my boyfriend because of a dream?

So I had a dream about this guy I had a crush on years ago, and nothing happened in the dream besides sharing heart shaped snacks and being close, but what's weird is I remember it so vividly and it felt realistic. I normally don't remember my dreams that well. In a way I feel like I cheated on my boyfriend but I know that's not really logical because it was just a dream after all, but it still makes me feel super weird..
