SEX DREAM WITH EX BF

He is also my current partenr's ex good friend. He did a lot of horrible things to me and my current bf. But I have a dream about him EVERY SINGLE NIGHT for like the past week. It's been happening on and off for the past few months. It SUCKS. It's not always a sex dream but sometimes it is. What does that mean?! It's got me wondering about it. And wondering if I want someone with a funnier personality and a different connection. Idk maybe it's just making me paranoid. Should I tell my Bf....? How do I stop having these dreams...
