If dreamed you that you smoke, then in reality you will need to make a lot of efforts for achievement of a goal. If in a dream you have keen desire to light, then in real life you will face problems which can frighten you. However you should not be afraid of it because you are able to overcome everything. Dreams about smoking often dream people who decided to leave off smoking. In this case such dream means that you not up to the end gave up a habit which deeply sat down at your subconsciousness.
Be sure and keep any other thoughts out of your mind before drifting to sleep as a cluttered mind can decrease the chances that you will remember your dreams upon waking. Also, focusing on remembering your dreams upon waking in the morning is another very important thing. This sounds very easy, but is often hard for some to do.
