Why did I dream like this!!!?

So I've been in a relationship with my man for 4 1/2 years have our ups and downs like every relationship but we're happy and in love 😍 I made a female friend on Facebook and we instantly became friends we love all the same stuff and we feel like we've known eachtother forever and it's great! We've hung out a few times and it's always a good time. I am bisexual I had a very abusive relationship before my current boyfriend years ago and I really haven't looked into women much lately but yesterday night I had a dream where I was intimate with her! Idk why! I don't want anything with her I just want me and her to be cool you know?
