That's just what I was thinking!
On the day that I got sober, I was having a very vidid hallucinations of a huge snake wrapped around my body -- and I was trying to hold it's head back from biting me in the neck. For me, that snake represented my alcoholism.
The cool part of your dream? You were running AWAY from it!
Best wishes for you as you go through the day!
