What's happening in your body

In a study of nearly three hundred people who had stopped smoking one to four weeks earlier, a third reported at least one dream in which they smoked. In most of these dreams the dreamer catches themselves smoking and feels a jolt of panic or guilt. The dreams are more vivid than ordinary ones. The researchers called them dreams of absent-minded transgression and counted them as a withdrawal symptom, because almost none of the same people had had such dreams while they were still smoking.

What to expect

If you have one, the first minute after waking can be genuinely confusing, and the relief when it turns out to be a dream can be enormous. Some people take it as a sign that they secretly want to go back. The guilt in the dream points the other way. It is what a mind produces when not smoking has started to matter to it.

In the same study, if anything, these dreams were more common among the people who went on to stay stopped. They can keep coming for a while. Among people a year into not smoking, most remembered having them, and about a quarter of the dreams came after the sixth month. So one in month five is not a setback either; it is the old pattern playing out at night, and it changes nothing about the day.

What else you could do

It is a good marker to find when you scroll back through these weeks later. If the dream leaves a craving behind in the morning, start the day with something that breaks the old order. Get up straight away, drink water, open the window, or take the minute of breathing in SOS before the coffee. There is nothing else to fix.
