Good luck with keeping sober! Have you quit drinking before? Do you have any other peer support or tools besides your big book link? There are a lot of pitfalls out there, so it's good to be aware of them, often times people find face-to-face meetings or counceling to be helpful- this place is also good for support!
As for the nightmares, that's the least of your problems...but yep, nightmares (very vivid) used to shake me to the core. They are far less frequent now but I still wake up screaming and have nightmares, and I'm over 10 months sober. That all varies and it's quite manageable and common.
