A few months ago, I started having intense drinking dreams. I'd wake up and literally sigh in relief when I realised that it'd "only" been a dream.
My therapist encouraged me to talk about them. And, eventually, I had to admit to myself that -despite having experienced lots of enjoyable sober time- maybe a part of me still wanted to drink.
It was a blow to my ego and very discouraging. Eventually, though, I began to see that, yeah, a part of me would love to do it.. and I started accepting this reality, instead of fighting it. It's like I came to terms with it - I truly embraced it, and said "sorry, but it ain't gonna happen". I began to learn my limitations and be okay with them.
Sorry if this sounds esoteric, though I'd chip in, it's just what worked for me, it might not be your case at all 
Gneiss.
ps forgot to mention, after this self-acceptance process, the dreams stopped
