I have had them too- one really early, I think in the first 6 months, that I could tell you every detail about. I have a couple others I recall sort of, but they weren't scary traumatic like the first one or two. With time, I now just have weird funny or weird dreams like I did way before my drinking days. Nine months is awesome, and still so early for our brains to be processing sobriety and emotions and such.
Hang in there.
