I get this too, I have gotten blood work done and it shows nothing, and I am not on any meds. Sometimes it happens when I sleep to much. But other times it just happens. Is like everything around me is going by so slow, and I'm going even slower. I feel like a zombie or puppet like you said And i have trouble with concentration and my speech (trouble finding words, loosing train of thought, stuttering). It's almost as if I am on some sort of drugs. It's strange! I wish I knew what caused it too.
