Hi and sorry to hear you are having a hard time.
When I was in a long term treatment years ago. They told me dreams are just your mind getting rid of the crap in your head. They said that is why some people that drink all the time are stressed because you don't sleep right. A person that is drunk does not go into a deep sleep. And you need to get that deep sleep to dream. Said that is why some alcoholics cannot fuction well.
I hope you will see the good side of sobrity. It is so worth it.
