Ok. I guess occasionally that has happened to me, but I knew them to be real. When I drink, even if not much, I sometimes don't really care about being there and a part of me does. The memories of those nights tend to come a day to max a week later, more like an fyi. Doesn't happen often, not at all in the past 2 years or so.
I don't really mind it. The memory that didn't happen was far more difficult to handle, and still is, to some extend.
