the only thing I noticed was the return of dreams

Same thing happened to me. I quit wake-and-baking about five and a half years ago because I felt it had just taken over too much of my life. Shortly afterward I became a school bus driver, which requires an initial drug screening and then you're subject to random tests thereafter. I'm a little pissed that I've never been selected for the random test, which means I could have been happily puffing away for the last five years.

The dreams are insanely weird and happen every time I sleep, even just a short nap. Most of the dreams are about me messing up driving a school bus and losing my job; one dream was me driving through high school hallways with kids scattering in all directions while thinking I really shouldn't be doing this. I never dreamed at all when I was smoking.
