Dreams about my ex, do I tell my husband?

At the very beginning of our relationship 3 years ago I was not really dating more sleeping around with my ex boyfriend Mike. We have been on again off again bf/gf for almost 4 years the last year was more friends with benefits than actual dating. So I ended things with him after about a month of dating my husband. We've been married 5 months. All this week and a few times since I've had vivid intimate and nonintimate almost "flashback" dreams. It's eating me up, I've talked to friends about it but idk if I should talk to my husband about it too. Any ideas about what I should do?
