I'll be 14 months sober in a few days and I notice I've had something very similar to your experience and so can relate to that.
I've had some restless dreams lately (and bizarre). In the dream when I remember it I walk a road and I hold a bottle of beer in my other hand and wonder what it is doing there. There are thoughts of 'hey, got to have something to drink for the morning'. Just complete nonsense.
I also recognize that this is something very similar to what took place in earlier sobriety. Maybe it's some kind of cycle of adaptation and brain chemistry. It sure looks that way now that I'm not the only one who's had that kind of dreams and disturbance.
So yeah. It propably is recovery related.
