Smoking cigarettes in your dreams when you don't do it in real life may mean you are emotionally troubled. Smoking is a repellent, it turns people off and pushes them away. Your dream could symbolize the fact that you have a hard time letting people in and so you push them away. Your mind is trying to work through the emotional problems that you won't work on yourself during the day.
I have been having recurring dreams about getting another tattoo. I already have one & love it. I have been conflicted about wanting another in waking life, but in my dreams I get very large ones (which I wouldn't ever do) in very visible places & in the dreams I always like how they turn out. However I never get the same tattoo twice. If you think you can help me with what that means I would love your feedback as well.
good luck with figuring out your dreams!
