I have a hard time remembering my dreams, but I am going to bet I smoke in some of them. I did dream about drinking when I quit, my most annoying dream being going to a party, drinking what I KNEW was not alcohol, and getting drunk anyway. I roamed the party in a cold sweat, wondering what was going on. When I woke up, my first thought was, "How unfair, I totally TRIED not to get drunk and did anyway." LOL.
These type of dreams are not uncommon in the beginning, or even sometimes later. I know they did a study on folks who wound up in wheelchairs, and IIRC, it took between a year to about 10 before folks no longer dreamed of "walking." If a huge change happens in your life, well it takes some time for your subconscious to adjust, as it were. I kind of felt sad knowing that even folks who have become paras, will eventually stop dreaming they walk. Although I don't know if that situation is painful, or welcomed. I guess it could be either.
I just started ignoring my dreams, and mostly don't remember them. I was going
through a bad time and got sick of the nightmares. I kind of view sleep as "blissful whiteout" these days. LOL.
