<human>: My ex boyfriend broke up with me about three weeks ago to pursue his coworker.  I had made a post about it, here is the link:

A day later, I was feeling pretty good and posted an update about it which is here:

I think I've been handling everything pretty well, my anger has faded a little bit.  I've been keeping busy with work and activities and ultimately I understand that I'm much better off without him.  However, I keep having nightmares and dreams about him.  

In these dreams he always shows up where I am, usually at my home.  It started out with him breaking up with me over and over again, then they progressed to being more malicious.  He would point out all of my flaws but they didn't have any grounds to them.  Things like "you're always cold" would come up. In the next round of dreams he would be apologetic and try to come back but it would end horribly with me either turning him down, or a family member getting upset about him being back in the picture.  Now I'm having dreams of him bringing his new lover(s) back to my own home and having relations with them in my bed and other places while (in my dream) I'm still under the impression that we're dating.  In this last dream I started punching him and trying to physically hurt him and it wasn't at all satisfying.  I just woke up feeling hurt and upset. 

I know this is probably my sub conscious dealing with what happened but I wish it would stop.  I want to move on and forget about him.  Waking up angry and upset with him I feel is only holding me back.  Has anyone experienced this?  Does it get better and are there tips to help prevent them?  I haven't slept very well since the breakup,  it would be cool to get some decent rest.

Could you distill the essence of the text into 1-3 sentences?
<bot>: Upsetting dreams about ex-boyfriend are causing me to re-live how he hurt me.  I just want rest.
