I completely understand the dreams; mine are always of me trying to hide my beer from my husband or of being so drunk that I forget to even try to hide them and he opens the refrigerator to find dozens and dozens of beer cans in there. I had those dreams usually when I "secretly" relapsed (or so I thought I secretly did). They stopped after about a week of quitting but I still remember the guilt and panic I felt waking up from them. As for why you're having yours, I wish I could offer some sort of suggestion that was concrete. I think, in the same way our minds differ from others' where drinking alcohol is concerned, they also differ in the way they help us work through the chaos we've created.
Either way, congratulations on 52 days!
