The dreams are very disturbing, I had them all throughout 2014 and into early 2015. Hang in there, the dreams do seem to go away after a while. Addiction seems closely "tied into" the subconscious mind. If it matters, from time to time I also have bad dreams about bad events from the past (teenage years. family stuff, a job I worked at, etc), so I take it that alcohol is not the "only" thing that embeds itself in the subconscious.
At least, I haven't had an "alcohol dream" in a long time
