Why am I suddenly dreaming about XN?

It's been almost ten months since my D and D. This has been the year from hell, the worst of my life. But I am finally starting to feel a little bit better.

So why am I now, all of a sudden, dreaming about XN? It is happening almost every night, and in these dreams, we are friends again...like we were before our liaison.

We will never be friends, or anything, again. That ship has sailed, But the dreams are rattling me. I am waking up moody and upset. And today I have been crying on and off all day, like I was doing six months ago.

What's going in here? Has this happened to anyone else? Help, please!
