I wouldn’t worry about it too much if it isn’t causing you stress or harm while you’re awake. I quit smoking several years ago now and in almost every dream I recall having, I just have a cigarette a lot of the time in addition to whatever else is going on. Sometimes it actually enters into the dream, a lot of the time not.

I don’t notice any effects from this like increased craving. I think it just means there’s a little part of me that misses the heaters; I’d be lying if I said I never thought about having one, you know?
