I have certainly had my fair share of drink dreams - I recently dreamt about being in a restaurant, ordering a glass of red wine and then sending it back, since I remembered I couldn't have it. I have also dreamt about breaking my sobriety.
My rehab after-care therapist said that drink dreams are extremely common in early sobriety. The important thing is that you're still not drinking in reality. The subconscious can do some weird things - I certainly have some dreams about my past that I don't want to revisit, as Dee has said. You will be fine.
Getting over the first few days is one of the toughest hurdles, and you have managed it. You should be congratulating yourself
. Don't beat yourself up about something that isn't even real.
Hang in there and best wishes.
