I also had very vivid and what seemed very real dreams about bad things that happened from drinking. Only had 2 of them about a month after I quit drinking as well. They seemed to contain parts of my life that I was angry, sad, disappointed and afraid of all wrapped up into one dream. Like all the events in my life that I had issues with and the anger that was present when me and my Girlfriend would argue and just pure nastiness was all wrapped in to one dream. When I woke up from them, I had thought them real and it was like waking up from a nightmare. I found a great counselor and I asked about them. He said they are called "using dreams" and very common in the first 1-6 months of sobriety, some people have lots of them, some never do. I just know the 2 that I had scarred the crap out of me in how ugly the were.
