This is not unusual. The brain processes and organizes information when we sleep, just that we don't all usually remember this happening. I find that I tend to think about things in my sleep on three occasions: 1 when the activity is new 2.when I am sufficiently stimulated and excited by the material. 3. when I am worried or upset This 'dream state'used to occur to me in the past when I actively played chess, when I was in school studying for exams and nowadays when I'm struggling with (and mastering) a new concept or paradigm in programming. Recognizing it for what it is - a process of deep archiving and reorganization, I have come to embrace it and even be happy when it occurs, since material I have processed in this way terms to be deeply ingrained in my memory for longer.
