What does it mean when you dream about your ex who had a rough sex and in your dreams he has sex with someone else symbolize having sex with another person they fell down the steps in front all his?

This dream only suggests that you have lingering emotional ties to your ex, and that you continue to think of him as your sexual partner. The dream seems to be your own mind's attempt to show you that there is nothing left for you in that relationship and that it is time to move on with your life.
