It means she enjoys smoking. Probably wishes that you'd start so she won't get hasseled. Sharing the experience with her will improve both your lives. Who needs crying and/or guilt..
That she wishes the comfort of death more than pains of life. Their is nothing you can do to intervene but aggravate and spread its influence. You see just as their is an angel for every new growth of life their is a demon that can invade and claim its grounds with a veracity for all to see and too marvel at and too despise.
She is a hopeless addict.
i think its an unconsious fear that you have,you are unconsiously fearing your mom might start smoking again?
you probably went to sleep thinking about it which means it was on your mind subconsciously. I dont think it will mean that she will start smoking again
