I have had loads of drinking dreams, some of them, I actually drink, others, someone is trying to get me to drink. (usually its my parents trying to get me to drink because they still don't like/don't accept that I am a recovering alcoholic)
Anytime I wake up from one where I didn't drink I usually wake up super annoyed at that person in the dream who actually offered me the alcohol.
If I wake up from one where I actually drank, I get super sad, disappointed in myself, angry, etc etc.
