I had smoking dreams all the time early on in my quit. I usually woke up depressed feeling like I had relapsed and it took a moment to figure out that it was just a dream. One dream was so clear, and weird, that I posted what I remembered on QSMB, the quit site I was on before here.
I still occasionally have smoking dreams. The last one I remember, I actually fought through the cravings I was dreaming about and didn't smoke. Most of the ones I remembered ended with me smoking.
In the awake world, I feel no temptation to smoke. I have occasional thoughts about lighting up but they are so weak that I can push them out of my mind real easily. They definitely are not craves like I had early on.
I guess occasionally re-living smoking in a dream is a sign of how much a part of our lives feeding that addiction used to be. As long as you stay smoke free in the awake, real world, you are good.
