Cant stop dreaming about him

It's been several months of no contact and things are well. I don't think about him as much nor do I cry..

But I cannot stop dreaming about him, every night without fail. I dream that he comes back to me and apologizes and we get back together, and I'm SO HAPPY. Literally the happiest I've ever felt. Every single night.

Has anyone else dealt with this? I'm tired of the emotional whiplash of waking up to this.
