any thing is possible, but that has not happened to me. I have done things I don't remember doing, which is more common then what your describing. Perhaps some thing else was weighing in on your mind? I love ambien. but my pdoc doesn't want me taking it and klonopin. I would be careful with ambien it is a hypnotic and you should only take it just minutes before you go to bed. Otherwise strange things can happen. People have even driven off in their car and not remember it. Or went on walks, or did and said things they didn't remember doing.
