Dreaming about other men

So, I’ve been married for three year. I love my husband so much! And we’re actually pretty happy with our life. But, for the past two nights I’ve been dreaming about being with another man. Like in the dream we’re dating, making out, and having fun. What could these dreams mean? I love my husband so much, so I’m confused at to why these dreams happen.

Note: I don’t know the men in my dreams.
