Perfectly normal. My drunk dreams would come and go the first couple of weeks. I havn't had one in a while but when I do I know it's just a reminder for where I no longer want to go. Wish your friend well for us!
I used to "think" I was more creative and would help hubby with his music, but in hindsight, most of what I did when I looked at it was virtual crap!.... however, I don't condone it, but I know artist's who draw and paint "think" they get their greatest inspiration when buzzed. I look at it as letting go which we learn to do sober/clean.
